摘要
Quantitative conversion: Reaction of the 14-electron complex [RuCl 2{(2,6-Me2C6H3)PPh2} 2] with CH2O in the presence of NEt3 gave a five-coordinate cyclometalated complex with a δ-agostic interaction of one ortho-methyl group (see X-ray crystal structure), Displacement of one phosphane group with 2-(amino-methyl)pyridine gave a highly active catalyst for the quantitative conversion of ketones into alcohols.
