www.acs.orgaldehydes, ketones and epoxides. LiBH 4 SODIUM BOROHYDRIDE Reduces aldehydes and ketones to corresponding alcohols. Sodium borohydride is not reactive to esters, epoxides, lactones, carboxylic acids, nitro compounds and nitriles, but reduces acyl chlorides. In combination with CeCl 3 allows for selective reductions of α,β-unsaturated ...
