A general synthesis of homodinuclear μ-alkylidene complexes of tungsten, starting from Fischer type alkylidene complexes of tungsten is outlined.Thus the vinyl-alkylidene complexes (CO)5W=C(OMe)CHCHR react with (CO)5W=CPh2, as a source of coordinatively unsaturated w(CO)4, to give the dinuclear complexes W2(CO)9(OMe)CHCHR, and the complex (CO)5W=C(OMe)CHCH2 reacts slowly in hydrocarbon solution, in the absence of (CO)5W=CPh2, to give a dinuclear complex W2(CO)19C(OMe)CHCH2 in which the two metal centers are not bound together: this product is the result of coordination of the double bond of the starting material to a W(CO)5 species.
