A manganese-catalyzed chemoselective hydroboration of carboxylic acids to the corresponding alcohols offers a high turnover number and turnover frequency at 25C. This method tolerates electronically and sterically differentiated substrates with high chemoselectivity. Importantly, aliphatic long-chain fatty acids, including biomass-derived compounds, can efficiently be reduced.
