Bimetallic-Catalyzed Reduction of Carboxylic Acids and Lactones to Alcohols and Diols
[Rh(acac)(CO)2] and [Mo(CO)6] showed the highest activity and was therefore applied to the reduction of lactones to diols. The reduction potential of the catalyst was found to be dependent on the ring size of the lactone used. Five-membered ring lactones were hardly converted to diols whereas six- and seven- membered ring lactones reacted easily.
