    Two kinds of ansa derivatives, [SiMe2(η5-C5H4)2]MCl2 and [CMe2(η5-C5H4)2]MCl2 (M = Mo, W), are reacted with metallophosphide anions [PPh2M‘(CO)x]- (M‘ = Cr, Mo, W, x = 5; M‘ = Fe, x = 4). The silicon-bridged derivatives give the bimetallic systems [SiMe2(η5-C5H4)(η5-C5H3PPh2M‘(CO)x)]M(H)(Cl), which result from a regioselective substitution at the 3-position on the cyclopentadienyl ligand.

    Reaction between [MCl(4)(dme)] (M = W or Mo; dme = 1,2-dimethoxyethane) with Li-2[C(5)H(4)CMe(2)C(5)H(4)] gave the ansa-bridged metallocene dichlorides [M(eta-C5H4)CMe(2)(eta-C5H4)}Cl-2] (M = W or Mo). Treatment of these with LiAIH(4) or ZnMe(2) gave respectively the dihydrides [M(eta-C5H4)CMe(2)(eta-C5H4)}H-2] (M = W or Mo) and the dimethyl derivatives [M(eta-C5H4)CMe(2)(eta-C5H4)}Me(2)] (M = W or Mo). Treatment of [W(eta-C5H4)CMe(2)(eta-C5H4)}Me(2)] with HX (X = PhCO(2) or NH3I) gave [Weta-C5H4)CMe(2)-(eta- C5H4)}Me(Y)] with Y = PhCO(2) or I, respectively. Both of these react with Na[AIH(2)(OCH(2)CH(2)OMe)(2)] giving the methylhydride [W(eta-C5H4)CMe(2)(eta-C5H4)}Me(H)]. The latter is thermally stable in refluxing benzene. Ultraviolet photolysis of [Mo(eta-C5H4)CMe(2)(eta-C5H4)}H-2] in benzene gave the phenylhydride derivative [Mo(eta-C5H4)CMe(2)(eta-C5H4)}Ph(H)]; the corresponding tungsten derivative [W(eta-C5H4) -CMe(2)(eta-C5H4)}H-2] is not photosensitive. The crystal structures of [W(eta-C5H4)CMe(2)(eta-C5H4)}Cl-2], [W(eta-C5H4)CMe(2)(eta-C5H4)}H-2], (two modifications) and [Mo(eta-C5H4)CMe(2)(eta-C5H4)}H-2] have been determined by X-ray diffraction. The ansa-bridged bis(eta-cyclopentadienyl) compounds show marked differences in reactivity compared to non-ansa analogues and this is discussed in terms of the modifications of the electronic structure as a consequence of the ansa bridge.
