A new green protocol for the synthesis of 2-substituted perimidines from hydrazones under catalyst- and solvent-free conditions

Abstract

A new green protocol was developed for the synthesis of 2-substituted perimidines. The protocol involves a reaction of ethoxy carbonylhydrazone with 1,8-diaminonaphthalene under solvent- and catalyst-free conditions. Simple workup procedure, economical and environmentally benign are the most advantages of the present method. © 2018 Bulgarian Academy of Sciences, Union of Chemists in Bulgaria
