Aryl N-aroxycarbonyltrichloroacetimidates (Ar = Ph, 4-FC6H4) react with diphenylphosphinite according to the scheme of the aza-Perkow reaction to give the corresponding aryl N-(1-aroxy-2,2-dichloro-vinyl)-N-diphenylphosphinoylcarbamates. The structure of one of these compounds was confirmed by single crystal X-ray diffraction analysis. In the case of electron-accepting substituents (Ar = 4-O2N6H4), the primary product undergoes mild β-elimination to give nitrophenyl diphenylphosphinate and 1-nitrophenoxy-2,2-dichlorovinyl isocyanate. The reaction of trichloroacetimidates with triethyl phosphite yields a mixture of O- and N-phosphorylation products.
