Triphenylphosphine dichloride reacts with (Me3Si)2CNN, Me3SiNCNSiMe3, and metal-coordinated CNN(SiMe3)2 to give the iminophosphoranes CNNPPh3, NCNPPh3, and W(CO)5CNNPPh3, respectively, and with free bis(trimethylsilyl)isocyanamine to give a dicationic species containing a tetrazole ring with triphenylphosphonio and bis(triphenylphosphonio)methylide substituents. This latter product can be regarded
与(ME二氯化三苯基膦发生反应3 Si)的2 CNN中,Me 3 SiNCNSiMe 3,和金属配位的CNN(森达3)2,得到亚氨基正膦CNNPPh 3,NCNPPh 3,和分别用W(CO)5 CN = NPPh 3和游离的双(三甲基甲硅烷基)异氰胺制得含有三唑膦基和双(三苯膦酰基)亚甲基取代基的四唑环的双键型物质。后一种产物可视为重氮亚甲基三苯基膦烷的环二聚产物,NNCPPh3。二聚体的结构已经通过X射线晶体学确定。
