A reaction between (C5H5)P(C6H5)2 and TlOEt in ethyl ether produces Tl in quantitative yield.Treatment of (η5-C5H5)TiCl3 with Tl affords (η5-C5H5))TiCl2 in 95 percent yield.Reductive carbonylation of the latter complex yields (η5-C5H5)5-C5H4P(C6H5)2>Ti(CO)2.Both of these phosphine-substituted titanocene derivatives react with (η5-C5H5)(CO)2(THF)Mn to generate the respective bimetallic complexes (η5-C5H5)(CO)25-C5H5)5-C5H4P(C6H5)2>TiCl2>Mn and (η5-C5H5)(CO)25-C5H5)5-C5H4P(C6H5)2>Ti(CO)2>Mn in good yield.In the presence of air, the latter complex undergoes facile decomposition to yield (η5-C5H5)Mn(CO)2.The crystal and molecular structure of the bimetallic complex (η5-C5H5)(CO)25-C5H5)5-C5H4P(C6H5)2>TiCl2>Mn has been determined by X-ray diffraction methods.
