An Unexpected Mechanism of Hydrosilylation by a Silyl Hydride Complex of Molybdenum
Carbonyl hydrosilylationcatalyzed by (ArN)Mo(H)(SiH2Ph)(PMe3)(3) (3) is unusual in that it does not involve the expected Si-O elimination from intermediate (ArN)Mo(SiH2Ph)((OPr)-Pr-i)(PMe3)(2) (7). Instead, 7 reversibly transfers beta-CH hydrogen from the alkoxide ligand to metal.
