| [4+2]-Cycloadditionen von Phospheniumkomplexen des Typs C p (O C)2W = P R 2 (R = Alkyl, A ryl) mit 2,3-Dimethylbutadien Phosphenium Complexes, X X IX [1], [4+2]-Cycloaddition of Phosphenium Complexes of the Type Cp(OC)2W=PR2 (R = Alkyl, Aryl) with 2,3-Dimethylbutadiene The phosphenium complexes Cp(OC)2W=PR2 [R = Ph, o-Tol, Me, t-Bu, (2a -d)] react with 2,3-dimethyl-1,3-butadiene (3) via [4+21-cycloaddition to form the phosphametallacyclohexe nes Cp(OC)2W-PR2-CH2-CMe=CMe-CH2 (4a -d). The structure of 4a has been determined by X-ray diffraction. | | |
