Abstract

Abstract A number of 4, 5-dihydrobenzo [e] imidazo [2, 1-c][1, 4, 2] diazaphosphinine derivatives were prepared by the direct phosphorylation of 1-(4-Chlorophenylcarboxamido)- 2-(1H-1-imidazolyl)-5-trifluoromethylbenzene in basic medium with phosphorus (III) bromide and dibromophenylphosphine. The tricyclic compounds 6a, 6b, and 9 having a trivalent phosphorus atom undergo the diazaphosphinine ring opening upon treatment with ...
