2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Safety of 2-(Bromomethyl)pyridine hydrobromide

《Rotaxanating Metallo-supramolecular Nano-cylinder Helicates to Switch DNA Junction Binding》 was published in Journal of the American Chemical Society in 2020. These research results belong to Hooper, Catherine A. J.; Cardo, Lucia; Craig, James S.; Melidis, Lazaros; Garai, Aditya; Egan, Ross T.; Sadovnikova, Viktoriia; Burkert, Florian; Male, Louise; Hodges, Nikolas J.; Browning, Douglas F.; Rosas, Roselyne; Liu, Fengbo; Rocha, Fillipe V.; Lima, Mauro A.; Liu, Simin; Bardelang, David; Hannon, Michael J.. Safety of 2-(Bromomethyl)pyridine hydrobromide The article mentions the following:

A class of rotaxane is created, not by encapsulating a conventional linear thread, but rather by wrapping a large cucurbit[10]uril macrocycle about a three-dimensional, cylindrical, nanosized, self-assembled supramol. helicate as the axle. The resulting pseudo-rotaxane is readily converted into a proper interlocked rotaxane by adding branch points to the helicate strands that form the surface of the cylinder (like branches and roots on a tree trunk). The supramol. cylinder that forms the axle is itself a member of a unique and remarkable class of helicate metallo-drugs that bind Y-shaped DNA junction structures and induce cell death. While pseudo-rotaxanation does not modify the DNA-binding properties, proper, mech.-interlocked rotaxanation transforms the DNA-binding and biol. activity of the cylinder. The ability of the cylinder to de-thread from the rotaxane (and thus to bind DNA junction structures) is controlled by the extent of branching: fully-branched cylinders are locked inside the cucurbit[10]uril macrocycle, while cylinders with incomplete branch points can de-thread from the rotaxane in response to competitor guests. The number of branch points can thus afford kinetic control over the drug de-threading and release.

Visualizing and dynamic tracking lipid droplets (LDs) are of great importance to biol. research. Herein, two-photon absorption fluorescent small bioprobes based on lipophilic coumarin were developed, which exhibited high selectivity toward LDs in HeLa cells. Because of good biocompatibility and excellent photostability, the probes were applied to realize specific super-resolution visualization of the intracellular LDs in HeLa cells, offering us the quant. results of the amount and diameters of LDs as well. Furthermore, the bioprobes were capable of monitoring the movements of the LDs in real time. The authors believe that bioprobes would provide new avenues to designing bioimaging and biol. diagnosis.

In 2016,Popowski, Yanay; Goldberg, Israel; Kol, Moshe published 《The stereoselectivity of bipyrrolidine-based sequential polydentate ligands around Ru(II)》.Chemical Communications (Cambridge, United Kingdom) published the findings.Product Details of 31106-82-8 The information in the text is summarized as follows:

The Ru(II) coordination chem. of the sequential hexadentate, tetradentate and the novel hybrid pentadentate ligands assembled around the chiral bipyrrolidine core and including bipyridyl and pyridyl periphery units is described. The bipyridine group exhibited priority in binding over the bipyrrolidine group, which led to a diastereomer mixture in the case of the hexadentate ligand (R,R)-bis(bipyridinylmethyl)-2,2′-bipyrrolidine (1). Employing only monopyridyl or a combination of monopyridyl (3) and bipyridyl (4) peripheral groups restored the chiral induction ability to the bipyrrolidine core resulting in predetermined chiral-at-metal complexes.

Reference of 2-(Bromomethyl)pyridine hydrobromideIn 2019 ,《Facile synthesis and separation of E/Z isomers of aromatic-substituted tetraphenylethylene for investigating their fluorescent properties via single crystal analysis》 was published in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices. The article was written by Lu, Zhixiang; Yang, Shaoxiong; Liu, Xiaolan; Qin, Yu; Lu, Shuhan; Liu, Yanxiong; Zhao, Ruidun; Zheng, Liyan; Zhang, Hongbin. The article contains the following contents:

The intermol. interactions and mol. packing form of fluorescent mols. have a huge impact on their optical properties, especially for AIE mols. As a class of typical AIE mols., tetraphenylethene (TPE) and its derivatives have prominent optical properties; nevertheless, separation of mixtures of E/Z isomers is a great challenge. Herein, a series of aromatic-substituted TPE derivatives were synthesized and used to sep. mixtures of E/Z isomers by common column chromatog. with high yields, as confirmed by single crystal anal., mass spectrometry and NMR spectroscopy. The structure-property relationships of these mols. were systematically investigated by a combination of spectroscopic methods, theor. calculations and single crystal data anal. E/Z isomers exhibit many different fluorescent properties, such as AIE and mechanochromic behavior. Moreover, the position of N on the substituted pyridine ring also has an effect on the mol. stack pattern and the fluorescent properties. Collectively, our findings could not only improve the fundamental understanding of the cis/trans isomerization and photophys. properties of TPE derivatives but also provide a good strategy for designing different substituted groups that can produce various functions and have more potential applications.

Optimization of the nitrogen and oxygen element distribution in microalgae by ammonia torrefaction pretreatment and subsequent fast pyrolysis process for the production of N-containing chemicals

In this work, ammonia (NH3) torrefaction pretreatment (ATP) was developed to optimize the nitrogen and oxygen element distribution of microalgae via the N-doping and oxygen removal reaction, which could obviously improve the potential use of microalgae as a feedstock for the production of N-heterocyclic chemicals through fast pyrolysis technology. The nitrogen content increased from 8.3% of raw microalgae to 11.51% at 300 degrees C of ATP, while the oxygen content decreased from 35.96% to 21.61%, because of the Maillard reactions. In addition, the nitrogen-doping ratio and oxygen removal ratio of ATP was much higher than the conventional nitrogen torrefaction pretreatment (NTP). With the increase of ATP torrefaction temperature or the pyrolysis temperature, the relative content of the N-containing compounds increased, while the O-containing compounds decreased. For the N-heterocyclic chemicals, higher pyrolysis temperature favored the formation of pyrroles, while inhibited the formation of pyridines and indoles.

Activation of Protic, Hydridic and Apolar E-H Bonds by a Boryl-Substituted Ge-II Cation

The synthesis of a boryl-substituted germanium(II) cation, [Ge{B(NDippCH)(2)}(IPrMe)](+), (Dipp=2,6-diisopropylphenyl) featuring a supporting N-heterocyclic carbene (NHC) donor, has been explored through chloride abstraction from the corresponding (boryl)(NHC)GeCl precursor. Crystallographic studies in the solid state and UV/Vis spectra in fluorobenzene solution show that this species dimerizes under such conditions to give [(IPrMe){(HCNDipp)(2)B}Ge=Ge{B(NDippCH)(2)}(IPrMe)](2+) (IPrMe = 1,3-diisopropyl-4,5-dimethylimidazolin-2-ylidene), which can be viewed as an imidazolium-functionalized digermene. The dimer is cleaved in the presence of donor solvents such as [D-8]thf or [D-5]pyridine, to give monomeric adducts of the type [Ge{B(NDippCH)(2)}(IPrMe)(L)](+). In the case of the thf adduct, the additional donor is shown to be sufficiently labile that it can act as a convenient in situ source of the monomeric complex [Ge{B(NDippCH)(2)}(IPrMe)](+) for oxidative bond-activation chemistry. Thus, [Ge{B(NDippCH)(2)}(IPrMe)(thf)](+) reacts with silanes and dihydrogen, leading to the formation of Ge-IV products, whereas the cleavage of the N-H bond in ammonia ultimately yields products containing C-H and B-N bonds. The facile reactivity observed in E-H bond activation is in line with the very small calculated HOMO-LUMO gap (132 kJ mol(-1)).

Synthesis of bio-additive fuels from glycerol acetalization over a heterogeneous Ta/W mixed addenda heteropolyacid catalyst

The heterogeneous heteropolyacid-catalyzed acetalization of glycerol with acetone was investigated under solvent-free conditions. In this work, the calcined Ta/W mixed addenda heteropolyacid catalyst ({H-20}-355) was employed as a solid acid catalyst and showed much higher activity than these soluble Keggin-type catalysts in the acetalization of glycerol with acetone due to its superacidity (H-0 =-12.95). Meanwhile, it showed high stability in catalytic recycles and extended for acetalization of glycerol with the other aldehydes and ketones. Based on the catalyst characterization by X-ray diffraction (XRD), scanning electron microscopy (SEM), P-31 NMR spectra, FT-IR spectra, pyridine-absorbed FT-IR, and Hammett acidity functions (H-0) by UV-vis spectroscopy, it was found that the acidic strength of the Ta/W mixed addenda heteropolyacid was highly dependent on the contents of crystalline water that could be tuned by calcination temperature. Notably, the solid superacid catalyst {H-20}355 was swollen by acetone, exhibiting an interesting pseudo-liquid behavior, which served as a microreactor and facilitated the reaction. Furthermore, after the acetalization reaction of glycerol with furfural (98% yield of acetal) on {H-20}-355 catalyst, the furan ring of the acetal products can be hydrogenated sequentially into dioxolane or dioxane with Pd/C catalyst under room temperature condition without the need of any isolation procedure.
