Cycloaddition Reactions with Phosphenium Metal Complexes, 2. – Cyclized Phosphinidene(metallo)phosphoranes by Addition of “Methylphosphinidene” to Phosphenium and Arsenium Tungsten Complexes Cyclized phosphinidene(metallo)phosphoranes( 3a, b, 5 ) are obtained from Cp(OC) 2 W = ER 2 (E = P, As; R = t Bu, o Tol) (1a, b, 4 ) and (MeP) 5 ( 2 ). Treatment of 3a with CH 3 I yields the cationic η 2 ‐diphosphane complex( 6 ). The reaction of 3b with elemental sulfur and selenium leads to the four‐membered metallacycles(X = S, Se) ( 7a, b ).
