A mild, efficient and selective conversion of nitriles to amides is achieve
d by employing Amberlyst A-26 supported hydroperoxide, which is prepared in
situ from hydrogen peroxide and Amberlyst A-26 (OH- form). Nitriles and di
nitriles are transformed to their corresponding amides and diamides, respec
tively. Reactions proceed within 0.5-5 hr upon addition of a catalytic amou
nt of Amberlyst A 26(OH-) to a methanolic solution of nitrile and hydrogen
peroxide (35%), at room temperature.
