Abstrakt: The reaction of C,N-diphenylnitrilimine with a P-zwitterion derived from Pri3P and H2C=C(CN)CO2Et afforded the first representative of 2-pyrazolines containing the phosphonium group and products of the addition of nitrilimine to Pri3P and H2C=C(CN)CO2Et. The reaction of the P-zwitterion with C-4-nitrophenyl-N-phenylnitrilimine gave rise to a condensation product of one Pri3P molecule and two nitrilimine molecules. The three-dimensional structures of the compounds synthesized were established by X-ray diffraction analysis.
