Hydroboration reactions of carboxylic acids using sodium aminodiboranate (NaNH2[BH3]2, NaADBH) to form primary alcs. were systematically investigated, and the reduction mechanism was elucidated exptl. and computationally. The transfer of hydride ions from B atoms to C atoms, the key step in the mechanism, was theor. illustrated and supported by exptl. results. The intermediates, NH2B2H5, PhCH=CHCOOBH2NH2BH3–, PhCH=CHCH2OBO, and the byproducts, BH4–, NH2BH2, and NH2BH3–, were identified and characterized by 11B and 1H NMR. The reducing capacity of NaADBH was found between that of NaBH4 and LiAlH4. We have thus found that NaADBH is a promising reducing agent for hydroboration because of its stability and easy handling. These reactions exhibit excellent yields and good selectivity, therefore providing alternative synthetic approaches for the conversion of carboxylic acids to primary alcs. with a wide range of functional group tolerance.
