1,3-Dipoles of the type metallo nitrile ylide and metallo nitrile imine were prepared by mono-a-deprotonation of CH-acidic {[W(CO)5CHCH 2PPh3]PF6, M(CO)5CNCH 2CO2A (M = Cr, W; R = Me, Et), [Pt(Cl)(CNCH 2CO2Et)(PPh3)2]BF4} and NH-acidic isocyanide complexes (Cr(CO)5CNNH2) and were stabilized by coordination to a second transition metal complex fragment (Cr(CO)5, [M(CO)5]+ (M= Mn, Re), [FeCp(CO) 2]+, [Pt(Cl)(PR3)2]+ (R = Et, Ph)}. All dinuclear products 1-7, 10, and 11 are neutral species except [(Ph3P)2(Cl)Pt{μ2-CNCH(CO 2Et)}Pt(Cl)(PPh3)2]BF4 (8). Complex (OC)5W{μ2-CNCH(CO2Et)}Pt(Cl)(PEt 3)2 (5b) was characterized by X-ray diffraction. Twofold deprotonation/platination to give (OC)5Cr(μ3-CNC(Ph)} [Pt(Cl)(PPh3)2]2 (9) was achieved, in the case of Cr(CO)5CNCH2Ph.
