| Abstract: | Basic Metals. LXIV. Lewis-basic Bis(trimethylphosphine)cobalt Complexes with Indenyl and Trifluormethylcyclopentadienyl as Ligands The half-sandwich type compounds C9H7Co(PMe3)2 ( 1 ) and (C5H4CF3)Co(PMe3)2 ( 6 ) are prepared from CoCl(PMe3)3 and C9H7Li or TlC5H4CF3, respectively. They behave like metal bases and react with HBF4, CH3I (or CF3SO3CH3), I2, and CH3COCl by oxidative addition to give the cationic complexes [C9H7CoX(PMe3)2]+ and [(C5H4CF3)CoX(PMe3)2]+ (X ? H, CH3, I, COCH3) which are isolated as the PF6 salts ( 2–5 and 7–10 ). The 1HNMR and the IR spectra of the compounds 1–10 are discussed, also in comparison to those of the corresponding cyclopentadienylcobalt complexes. |
