Halide abstractions from P-chlorinated phosphorus ylides 9a-c either by AlCl3 or SnCl2 yield unsymmetrical methylene phosphonium ions 10a-c in which energy barriers > 83 kJ mol-1 for the rotation around the P=C have been estimated by NMR techniques.The salts with AlCl4- counteranions are stable, but compounds with SnCl3- anions decompose stereoselectively to unsymmetrical methylene phosphanes, SnCl2, and t-BuCl.
