A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 161265-03-8, Name is (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), molecular formula is C39H32OP2. In a Article，once mentioned of 161265-03-8, Safety of (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine)
Selective and efficient hydrosilylations of esters to alcohols by a well-defined manganese(I) complex with a commercially available bisphosphine ligand are described. These reactions are easy alternatives for stoichiometric hydride reduction or hydrogenation, and employing cheap, abundant, and nonprecious metal is attractive. The hydrosilylations were performed at 100 C under solvent-free conditions with low catalyst loading. A large variety of aromatic, aliphatic, and cyclic esters bearing different functional groups were selectively converted into the corresponding alcohols in good yields.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Safety of (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 161265-03-8, in my other articles.
