Liang, Qiuming; Song, Datong published an article in 2021. The article was titled 《Syntheses and Reactivity of Piano-Stool Iron Complexes of Picolyl-Functionalized N-Heterocyclic Carbene Ligands》, and you may find the article in Organometallics.Recommanded Product: 2-(Bromomethyl)pyridine hydrobromide The information in the text is summarized as follows:
[FeClCp*(HL)] (1; HL = 3-methyl-1-(2-picolyl)-imidazol-2-ylidene) was synthesized from the reaction of in situ generated HL ligand and [FeClCp*(TMEDA)] (TMEDA is N,N,N’,N’-tetramethylethylenediamine). The deprotonation of 1 with KHMDS led to removal of a pyridylic proton and the dearomatization of the pyridine ring of the HL ligand, forming [Cp*(L)Fe(μ-N2)FeCp*(L)] (2) under N2 or [(FeCp*)2(μ-H)(μ-L)] (3) under Ar. Complex 2 splits H2 across the L- ligands and the Fe centers to give [FeCp*(H)(HL)] (4). Complex 4 readily converts to [Cp*(L”)Fe(μ-N2)FeCp*(L”)] (5) under N2, where the L”- ligand chelates to the metal center through the carbene C and a pyridyl C. The reactions of 2 with PhSiH3 and Ph2SiH2 give silyl complexes 6 and 7, resp. Compounds of 2, 4, and 5 are active (pre)catalysts for the dehydrogenative coupling of dimethylamine borane. The results came from multiple reactions, including the reaction of 2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8Recommanded Product: 2-(Bromomethyl)pyridine hydrobromide)
2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8) belongs to pyridine. Pyridine is a relatively complex molecule and exhibits a number of different bands in IR spectra. Among others, the bands characterizing the ν8a and ν19b modes have been found to be sensitive to the coordination or protonation of the molecule. Note that the band that is diagnostic for the PyH+ ion at about 1545 cm− 1 (ν19b mode) does not overlap with any of the other bands.Recommanded Product: 2-(Bromomethyl)pyridine hydrobromide
