| Abstract: | ![]()
The naphthalene manganese complex [(η6-C10H8)Mn(CO)3]BF4 (1) has been used as an effective catalyst for the hydrosilylation of ketones to give the corresponding sec-alcohols in high yields after hydrolysis. The yields for aryl ketones are dependent on the reaction medium with the highest in CH2Cl2 and the steric bulkiness and electronic properties of substituents. As the steric bulkiness increases, the yield decreases and as the electron-donating ability of the substituent on the substrate increases, the yield increases. Catalytic activity of 1 is explained by the ring slippage η6→η4. |
