Resumen
The first thioalkyne derivatives of functionalised titanocene of formula [Ti(η5-C5H4R′)(η 5-C5H4R″)(SO≡CR)2] (R = But, R′ = R″ = SiMe3 1a; R = Ph, R′ = R′ = SiMe3 1b; R = But, R′ = SiMe3, R″ = PPh2 2a; R = But, R′ = Rn = PPh2 3a) have been prepared by reaction of [Ti(η5-C5H4R′)(η 5-C5H4R″)Cl2] and LiSC≡CR in diethyl ether. Complexes 1a and 2a have been used as precursors in the synthesis of Ti-M (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.
