the synthesis of 2-substituted1,3-benzoselenazoles by the reaction of bis(2-aminophenyl)diselenide with a wide range of carboxylicacids, promoted by tributylphosphine. This efficient reaction furnishes 2-aryl-1,3-benzoselenazoles in good yields and tolerates a variety of substituents at the aryl moiety of carboxylicacids. For the first time, 2-alkyl-1,3-benzoselenazoles could be obtained from aliphatic
