摘要 | The propensity of sodium borohydride to reduce the carbonyl group in eleven alpha-substituted and two aromatic esters has been investigated by experiments and at the B3LYP/631++G(d,p)//HF/6-3lG(d,p) level of theory. The chemoselectivities in nine of these reductions have been examined by experiments. Experimental results agree well with the calculated order of activation energies for hydride transfer to the ester carbonyl group. Methyl a-bromoacetate reduces faster than methyl a-fluoroacetate.
