Abstract
full title:Co-ordinative ability of the new compounds [Ti(η5-C5H4R)2-(C≡CBu t)2] (R = PPh2, Ph2P=O or Ph2P=S) as precursors in the synthesis of heterodi- And heterotri-nuclear species. Crystal structure of [ClCu(μ-η5 : κP-C5H4PPh2) 2Ti(μ-η2-C≡CBut)2CuCl] New mononuclear bis(alkyne) derivatives of functionalised titanocene [Ti(η5-C5H4R)2(C≡CBu t)2] (R = PPh2 1, Ph2P=O 7 or Ph2P=S 8) have been isolated by reaction of [Ti(η5-C5H4R)2Cl2] (R = PPh2, Ph2P=O or Ph2P=S) and LiC≡CBut in diethyl ether. The reactions of the former species with (CuCl)n and [Mo(CO)4(nbd)] have been investigated. Novel heterobi- [LnM(μ-η5 : κP-C5H4PPh2) 2Ti(̊-η2-C≡CBut)2] [MLn = CuCl 4 or Mo(CO)4 5], [{η5-C5H4P(E)Ph2} 2Ti(μ-η2-C≡CBut)2CuCl] (E = O 9 or S 10) and heterotri-nuclear complexes [LnM(μ-η5 : κP-C5H4PPh2) 2Ti(μ-η2-C≡CBut)2CuCl] [MLn= CuCl 2 or Mo(CO)4 6] have been synthesized. The crystal structure of compound 2 has been solved.
