electrophiles to provide derivatives containing only tungsten tricarbonyl units. These include W(CO)3(NH3)3, [W3(CO)9(μ-OC2H5)(μ3-OC2H5)2]3-, HW(CO)3(SnPh3)32- and the unusual [(Ph3Sn)2(Ph2Sn)2OEt}W(CO)3]−. The latter compound results from an unprecedented phenyl-tin cleavage in the reaction of triphenyltin chloride and the highly reduced carbonyltungstate ion. Triphenyltin derivatives of the unknown M(CO)36-

position. In all the η2-complexes, this double bond is stereospecifically coordinated by its exo-vs. endo-η4-Fe(CO)3 configuration was established by chemical correlation (hydrolysis, hydrogenation) with the corresponding complexes (24x, 24n) of 7,7-dimethoxy-2,3-dimethylidenebicyclo[2.2.1]heptane (5). The relative rates of hydrolysis (AcOH/H2O 2:1, 50°C) of ligands 2 and 5 and of complexes 19x, 19n, 24x
