The synthesis IR and 31P NMR spectra of the complexes of various N-aryltriphenylphosphinimines with some mercury dihalides as well as the corresponding phosphonium salts are reported It is shown by an X-ray crystal structure analysis of the complex of the unsubstituted phosphinimine with HgCl2 that in the solid state these complexes form dimers via two Hg...μ2 Cl...Hg bridges.

Several substituted methylaminotriphenylphosphonium salts (APS) of general formula +N(R)CH2R'>X- have been synthesized.The CH-acidities of some of the prepared APS have been measured by the indicator method in DMSO, with K+ counterion and 9-phenylfluorene (pK 18.5) as standard, showing a pK range of 14.7-24.8.The acidification effect of Ph3P+N(Ph) (?CH2- = 0.70) and Ph3P+N(Bu) (?CH2- = 0.68) groups has been evaluated.The results obtained suggest that there is an effective charge on the nitrogen atom in the APS studied and an increased multiplicity of the N-P bond.
