Abstract
The treatment of Cp(CO)(2)MeW{PN(Me)CH2CH2NMe(OMe)} with BF3.OEt2, followed by PPh3, yields trans-[Cp(CO)(2)(PPh3)W{PN(Me)CH2CH2NMe(Me)}] BF4, suggest ing that a cationic phosphenium complex is first formed and then migratory insertion of the phosphenium ligand into a W-alkyl bond takes place. In the reaction of the stannyl containing complex, Cp(CO)(2)(snR(3))W{PN(Me)CH2CH 2N-Me(OMe)}, with TMSOTf, an alkyl migration from Sn to a phosphenium P occ urs to give a stannylene complex.
