HCN phosphonium cyanidle I by reaction with the carboxylic acid), which reacts with the amine present to produce the corresponding amide and tri-n-butylphosphine oxide. The procedure is generally carried out employing 1.5 equiv of amine in tetr, ahydrofuran containing 1.5 equiv of o-nitrophenyl thiocyanate and 1.5 equiv of freshly distilled tri-n- butylphosphine. The reaction, which proceeds under mild conditions, has been performed ...
