A redox-active ligand-based Mn(i) catalyst initiates a single electron transfer (SET) to split the Si–H bond of PMHS leading to ester hydrosilylation under mild conditions.
We report the catalytic reduction of a C–Obond and the borylation by a rhodium complex bearing an X-type PAlP pincer ligand. We have revealed the reaction mechanism based on the characterization of the reaction intermediate and deuterium-labeling experiments. Notably, this novel catalytic system shows steric-hindrance-dependent chemoselectivity that is distinct from conventional Ni-based catalysts

complex [Ir(μ-CF3SO3)(κ2-NSiMe2)2]2 (3) (NSiMe2 = 4-methylpyridine-2-yloxy}dimethylsilyl) has been prepared by reaction of [Ir(μ-Cl)(κ2-NSiMe2)2]2 (1) with two equivalents of AgCF3SO3. The solid structure of 3 evidenced its dinuclear nature, being a rare example of an iridium species with triflate groups acting as bridges. The 3-catalyzed reduction of CO2 with HSiMe(OSiMe3)2 affords a mixture of the corresponding
