P(III)‐assisted electrochemical generation of isocyanates from hydroxamic acids was successfully applied in the synthesis of ureas. Hydroxamic acids were directly used without pre‐activation, and the reaction was found not sensitive to water or air. The process started with the anodic oxidation of hydroxamic acids, followed by reacting with trivalent phosphine to form corresponding alkoxyphosphoniums

synthesized in one-pot from carboxylic acids, diphenylphosphorazidate (DPPA) and benzotriazole (BtH). The reactivity and applications of carbamoyl benzotriazoles were also explored. Carbamoyl benzotriazoles react smoothly with amino acids, hydrazines and alcohols respectively, thus providing facile access to the corresponding ureas, hydrazinecarboxamides and carbamicesters in good to excellent yields
