An efficient synthesis of some new bisbenzimidazoles via microwave technique
(2014)
2,2’-[1,4 (1,3)-Phenylenedi(methylene)]bis-1 H -benzimidazole derivatives were obtained from the reaction of 1,4- or (1,3)-bisiminoester hydrochloride and o -phenylenediamine derivatives under microwave irradiation. Ester ...
Green protocol: Catalyst-free synthesis of 2-substituted benzimidazoles under ultrasound irradiation
(Science Reviews 2000 Ltd, 2018)
The synthesis of 2-substituted benzimidazoles from the reaction of o-phenylenediamine and an imino ester hydrochloride with ultrasound irradiation is reported. The procedure has an eco-friendly and simple workup with good ...
A new green protocol for the synthesis of 2-substituted perimidines from hydrazones under catalyst- and solvent-free conditions
(Bulgarian Academy of Sciences, 2018)
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 ...
