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-Chloro-phenylcarboxamido)-2-(1H-1-imidazolyl)-5-trifluoromethylbenzene in basic medium with phosphorus(III) bromide and dibromophenylphosphine. The amide was reacted with phosphorus(III) bromide to yield the tricyclic compound. The tricyclic compound with a trivalent phosphorus atom went through the diazaphosphine ring opening upon treatment with secondary amines in the presence of sulphur.
