ABSTRACT

3-(4-chlorophenoxy)-2,4-diisopropyl-2,3,4,5-tetrahydro-1H-benzo[e][1,3,2]diaza-phosphepine was synthesized starting from 1,2-bis(bromomethyl)benzene by reacting with 2 equimolar isopropyl amine, one equimolar PBr3 and then one equimolar 4-chlorophenol, respectively. The Staudinger reaction of the diazaphphosphine with a series of alkyl azides gave the corresponding iminophosphoranes. Antibacterial activities of the synthesized iminophosphoranes were screened
