New types of manganese(III) complexes containing H2salan ligand have been synthesized and examined as catalysts in the hydrosilylation of carbonyl compounds. Manganese(III) chloride complex (4b) exhibits minimal activity for the hydrosilylation of benzaldehyde at 120 ºC, but can be activated with silver perchlorate. Manganese(III) azide complex (5b) is characterized by the IR spectra, and the stretching frequency for the azide group is 2050 cm-1. This complex shows good activity in the hydrosilylation of benzaldehyde at 120 ºC, generating the corresponding silyl ether in high conversion 99 % within 1 h. Under optimized reaction conditions, phenylsilane as the reductant in C6D6 under nitrogen, the substrate scope has been examined. Several types of aldehydes and ketones can be reduced with tolerance to a variety of functional groups.
