Triethyl- or triisopropylborane/trifluoromethanesulfonic (triflic) acid is a convenient reagent for the selective reduction of hydroxy substituted carboxylic acids, ketones and aldehydes to yield the corresponding carbonyl compounds. The scope of the reaction, experimental conditions and suggested mechanism are discussed.
