Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, Quality Control of (S)-2-(2-Chlorophenyl)-2-(6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl)acetic acid hydrochloride, 144750-42-5, Name is (S)-2-(2-Chlorophenyl)-2-(6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl)acetic acid hydrochloride, SMILES is O=C(O)[C@H](C1=CC=CC=C1Cl)N2CCC3=C(C=CS3)C2.[H]Cl, belongs to pyridine-derivatives compound. In a document, author is Bariashir, Chantsalnyam, introduce the new discover.
Finely Tuned alpha,alpha ‘-Bis(arylimino)-2,3:5,6-bis(pentamethylene)pyridine-Based Practical Iron Precatalysts for Targeting Highly Linear and Narrow Dispersive Polyethylene Waxes with Vinyl Ends
One-pot template construction of alpha,alpha’-bis(arylimino)-2,3:5,6-bis(pentamethylene)pyridyl iron chlorides achieved by reacting alpha,alpha’-dioxo-2,3:5,6-bis(pentamethylene)pyridine and the corresponding anilines along with the respective iron chloride in acetic acid provided yields of 26-76%. All these complexes were characterized by FT-IR, elemental analysis, H-1 NMR, and X-ray diffraction analysis. Distorted-square-pyramidal geometries are observed in the molecular structures of Fe1 and Fe6, respectively. When MAO or MMAO is used as a cocatalyst, Fe1-Fe5 display a high activity of 10(7) g with highly linear, low-molecular-weight, and narrow-polydispersity polyethylenes (PEs) being obtained by ethylene polymerization. The catalytic activity of Fe1 reached a maximum activity ((3.81-3.93) x 10(7) g of PE (mol of Fe)(-1) h(-1)) by using the cocatalyst MAO or MMAO at Al/Fe ratio of 5000. All of the synthesized iron precatalysts Fe1-Fe8 containing sterically ortho benzhydryl and aryl (2,4,6-substituents of the aryl ring) groups delivered catalytic activities in the order Fe1 (Me)(2)CH(Ph)(2) > Fe5 Cl(CHPh2)(2) > Fe2 Me(CHPh2)(2) > Fe3 Et(CHPh2)(2) > Fe4 Pr-i(CHPh2)(2) >> Fe6 (CHPh2PrCHPh2)-Pr-i Fe7 (CHPh2BuCHPh2)-Bu-t approximate to Fe8 CHPh2 FCHPh2. Of note, this developed catalytic system was also used in scale-up ethylene polymerization with a high activity of up to 48.10 x 10(6) g of PE mol(-1).
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.
