Re2(CO)10 efficiently catalyzes the direct reduction of various carboxylic acids under UV irradiation at ambient temperature. While aliphatic carboxylic acids were readily converted to the corresponding disilylacetals with low catalyst loading in the presence of Et3SiH, aromatic analogues required more drastic conditions.
