The first thioalkyne derivatives of functionalised titanocene of formula [Ti(η5-C5H4Râ²)(η5-C5H4Râ³)(SCCR)2] (R = But, Râ²Â = Râ³Â = SiMe3 1a; R = Ph, Râ²Â = Râ³Â = SiMe3 1b; R = But, Râ²Â = SiMe3, Râ³Â = PPh2 2a; R = But, Râ²Â = Râ³Â = PPh2 3a) have been prepared by reaction of [Ti(η5-C5H4Râ²)(η5-C5H4Râ³)Cl2] and LiSCCR in diethyl ether. Complexes 1a and 2a have been used as precursors in the synthesis of TiâM (M = d6 or d8 metal) heteronuclear complexes showing different co-ordination modes. All compounds have been characterised by elemental analysis and 1H, 31P, 19F and 13C NMR and infrared spectroscopy. The crystal structures of two complexes have been solved.
式[Ti(δ-5-C5H4Râ²)(δ-5-C5H4Râ³)(SCCR)2](R = But, Râ²Â = Râ³Â = SiMe3 1a; R = Ph, Râ²Â = Râ³Â = SiMe3 1b.R = But, Râ²Â = SiMe3, Râ³Â = PPh2 2a; R = But, Râ²Â = Râ³Â = PPh2 3b;R = But, Râ²Â = SiMe3, Râ³Â = PPh2 2a; R = But, Râ²Â = Râ³Â = PPh2 3a) 是通过[Ti(δ-5-C5H4Râ²)(δ-5-C5H4Râ³)Cl2]和 LiSCCR 在二乙醚中的反应制备的。络合物 1a 和 2a 被用作合成 TiâM (M = d6 或 d8 金属)杂核络合物的前体,显示出不同的配位模式。所有化合物都通过元素分析、1H、31P、19F 和 13C NMR 以及红外光谱进行了表征。两个配合物的晶体结构已经得到解决。
