✦ Synopsis

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