Abstract: | Passage of CO through solutions of complexes (C6F5)2CoL2 gives carbonyl derivatives (C6F5)2CoL2(CO) (L2 = 2 PEt3, 2 P-n-Bu3, 2 PPh3, Ph2PCH2CH3PPh2). The properties of these compounds are described.The compounds are also produced by treating solutions of (C6F5)2Co-(dioxane)2 with CO, but a simultaneous reduction to (C6F5)Co(CO)4 takes place. Treatment of the latter complex with monodentate ligands gives substitution products (C6F5)Co(CO)3L (L = PEt3, P-n-Bu3, PPh3) all of which are monomeric, whereas the addition of Ph2PCH2CH2PPh2 gives the dimer (C6F5)(CO)2CoLLCo(CO)2(C6F5). The properties of these compounds are discussed. |
