Cycloaddition Reactions with Phosphenium Metal Complexes, 2. - Cyclized Phosphinidene(metallo)phosphoranes by Addition of “Methylphosphinidene” to Phosphenium and Arsenium Tungsten ComplexesCyclized phosphinidene(metallo)phosphoranes (3a, b, 5) are obtained from Cp(OC)2W = ER2 (E = P, As; R = tBu, oTol) (1a, b, 4) and (MeP)5 (2). Treatment of 3a with CH3I yields the cationic η2-diphosphane complex (6). The reaction of 3b with elemental sulfur and selenium leads to the four-membered metallacycles (X = S, Se) (7a, b).
