The reaction of lithium 1,2‐bis(diphenylphosphanyl)trimethylcyclopentadienide ( 1 ) with CpTiCl 3 leads to the formation of the titanocene diphosphane {(η 5 ‐C 5 H 5 )[η 5 ‐C 5 Me 3 ‐1,2‐(PPh 2 ) 2 ]TiCl 2 } (TiPHOS, 2 ). This metalloligand reacts readily with (NBD)Cr(CO) 4 and W(CO) 5 (THF) to give, in both cases, the bimetallic chelate complexes (TiPHOS)Cr(CO) 4 ( 3 ) and (TiPHOS)W(CO) 4 ( 4 ). The structure of 4 has been determined by X‐ray diffraction. The synthesis of a new early‐late heterobimetallic complex (TiPHOS)Rh(CO)Cl ( 5 ) is reported.
