Cyclic phosphinimines are strong bases with structural similarities to carbene ligands. The cyclic phosphinimines R2PNCPh 2(CH2CH(CO2Me)) (R = Ph 4, i-Pr 5, Me 6), R2PNCPh2(CCOMe)2 (R = Ph 7, i-Pr 8) and Ph 2PNCPh2(CH2CH(CN)) 9 are readily prepared via cycloaddition of the compounds R2PNCPh2 (R = Ph 1, i-Pr 2, Me 3) and olefins or alkynes. In the case of 4 this phosphinimine proved to be moisture sensitive, converting to Ph2C(NH2)CH(CO 2Me)CH2P(O)Ph210 upon hydrolysis. Nonetheless, the Ag(i) and Au(i) complexes [{Ph2PNCPh2(CH 2CH(CO2Me)}2Ag][NO3] 11 (Ph 2PNCPh2(CH2CH(CO2Me)AuCl 12 and (Ph2PNCPh2(C(CO2Me)2)AuCl 13 were prepared and characterized. Compounds 1, 2 and 7-13 have been characterized crystallographically.
