A bench-stable cobalt(II) complex, with 3N-donor socket-type benzimidazole-imine-2H-imidazole ligand is reported as a precatalyst for regioselective hydrosilylation of terminal alkynes. Both aromatic and aliphatic alkynes could be effectively hydrosilylated primary, secondary, tertiary silane to give α-vinylsilanes in high yields excellent Markovnikov selectivity extensive functional-group tolerance. Catalyst loading varies within 0.5–0.05 mol %, which one the most efficient so far...
Aryl boronic esters are bench-stable, platform building-blocks that can be accessed through metal-catalyzed aryl C(sp2)–H borylation reactions. bond functionalization reactions using rare- and precious-metal catalysts well established, while examples utilizing Earth-abundant alternatives have emerged, manganese catalysis remains lacking. The manganese-catalyzed C–H of furan thiophene derivatives is reported alongside an in situ activation method providing facile access to the active hydride...
Sodium triethylborohydride has been found to be a highly selective catalyst for the dehydrogenative silylation of aromatic and aliphatic alkynes with hydrosilanes.
The search for simple and easy-to-synthesize ligands bench stable cobalt (pre)catalysts that would ensure high activity selectivity in alkyne hydrosilylation reactions is an interesting current challenge. Herein, we report a cobalt(II) complex bearing pyrimidine-imine-2H-imidazole ligand activated by LiHBEt3 exhibits not only catalytic activity, but also unprecedented tolerance towards tertiary silanes highly regioselective Markovnikov of aliphatic aromatic terminal alkynes to give...
Geminal bis(silanes) are unique compounds with interesting properties. The most straightforward way to access them is double hydrosilylation of alkynes, which was established only recently. Previous articles about transition metal-catalysed show that terminal aryl alkynes a challenge. We report on cobalt(II) and iron(III) complexes the easy-to-synthesise N,N,N-tridentate hydrazone ligand being active precatalysts in Markovnikov-selective alkynes. influence structure potential role sodium...
A series of bench-stable Co(II) complexes containing hydrazone Schiff base ligands were evaluated in terms their activity and selectivity carbon-carbon multiple bond transfer hydrogenation. These cobalt complexes, especially a precatalyst bearing pyridine-2-yl-N(Me)N=C-(1-methyl)imidazole-2-yl ligand, activated by LiHBEt3, successfully used the hydrogenation substituted styrenes phenylacetylenes with ammonia borane as hydrogen source. Key advantages reported catalytic system include mild...
Alkoxysilanes find application in many areas of chemistry ranging from research-scale organic synthesis to multi-ton production materials. Classically, they are obtained stoichiometric reaction alcoholysis chlorosilanes, however, recent years brought development the field direct dehydrogenative coupling hydrosilanes with alcohols, which is a more atom-economic and benign alternative former process. In this paper, we report use sodium tri(sec-butyl)borohydride as convenient promoter reaction....
