The iminophosphane (Me3Si)3C-P=N-MeS* (1) reacts with iodine to form the imino(inethylene)phosphorane I-P(=N-Mes*)=C(SiMe3)2 (2). Upon subsequent treatment with AgCl, the corresponding chloro derivative 3 is obtained. Chlorine/bromine exchange in 3 with bromotrimethylsilane affords the bromo analogue 4. The structures of 2, 3 and 4 were confirmed by X-ray crystal structure analysis; each of the compounds features a trigonal-planar phosphorus atom.
