Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Category: pyridine-derivatives, 16063-70-0, Name is 2,3,5-Trichloropyridine, molecular formula is C5H2Cl3N, belongs to pyridine-derivatives compound. In a document, author is Chung, Lai-Hon, introduce the new discover.
Isolation of a C3-metalated indolizine complex and a phosphonium ring-fused bicyclic metallafuran from the osmium-induced transformation of pyridine-tethered alkynes
The first C3-metalated indolizine complex was prepared from the reaction between cis-[Os(dppm)(2)Cl-2] (dppm = 1,1-bis(diphenylphosphino)methane) and propargylic pyridine, HCCC(OH)(2-py)(2). A phosphonium ring-fused bicyclic osmafuran complex was also prepared from the reaction between cis-[Os(dppm)(2)Cl-2] and pyridyl ynone, HCC(CO)(2-py). The formation of these two products revealed the intermediacy of metal-vinylidene species regarding [Os(dppm)(2)Cl](+)-mediated alkyne transformations. Comparison of the d(6) transition-metal precursors employed to activate HCCC(OH)(2-py)(2) suggests that precursors with higher pi-basicity favor the vinylidene-involving pathway.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 16063-70-0. Category: pyridine-derivatives.
