WebA manganese-catalyzed chemoselective hydroboration of carboxylic acids to the corresponding alcohols offers a high turnover number and turnover frequency at 25°C. This method tolerates electronically and sterically differentiated substrates with high chemoselectivity. WebLAH is the most powerful in this class of reducing agent and readily converts carboxylic acids and their salts to primary alcohols in diethyl ether or THF at low temperatures. All carbonyl and carboxylic acid derivatives are readily reduced, as …
