In this study, we developed a method for the rapid reduction of acyl chlorides to aldehydes using pinacolborane (HBpin) as the reducing agent. The method exhibits excellent generality for both aromatic and aliphatic substrates, affording aldehydes in isolated yields of up to 88% with broad functional group tolerance, including cyano, halogen, alkenyl, ketone, and ester groups. Moreover, the method enables gram-scale aldehyde synthesis and shows high efficiency in reducing in situ generated acyl chlorides, thereby enhancing its synthetic practicality.

Key words: Pinacolborane, reduction, acyl chlorides, aldehydes
