The cation 4 can be obtained in an amazingly simple raction sequence from phosphorus trichloride 1 and the arylamine 2 via the iminophosphane 3 . Spectroscopic findings—δ( 31 P) = 79.3—and structural data—PNC angle = 177°, PN distance = 147.5 pm—suggest the presence of a triple bond, whereby 4 is isoelectronic with :SiN–aryl.
