摘要：

Reactions of metallophosphide anions [(CO)(x)M'PPh2](-) with molybdenocene and tungstenocene dichlorides Cp-2'MCl2 (M = Mo, W; Cp' = eta(5)-C5H4-tert-Bu) give Cp-ring 1,3-disubstituted products. Due to planar chirality associated with an asymmetric metallic center, diastereoisomers are produced but a fast interconversion process occurs allowing the isolation of only one isomer. Molybdenum complexes do not transform into orthometallated products as. was previously observed for their C5H5 or C5H4-Me analogs. Chemical reactions have been performed on the complexes 3' and 4'. Therefore reduction into dihydrides leads to mu-hydrido structures.
