Manganese Salan Complexes as Catalysts for Hydrosilylation of Aldehydes and Ketones

Manganese has attracted significant recent attention due to its abundance, low toxicity, and versatility in catalysis. In the present study, a series of manganese (III) complexes supported by salan ligands have been synthesized characterized, their activity as catalysts hydrosilylation carbonyl compounds was examined. While chloride exhibited minimal catalytic efficacy without activation silver perchlorate, azide showed good compounds. Under optimized reaction conditions, several types aldehydes ketones could be reduced with yields tolerance variety functional groups. The possible mechanisms silane were discussed light relevant experimental observations.
