Description
| - New phenyltetramethylcyclopentadienyl trinuclear titanocene hydride - magnesium hydride complexes [{Ti(.eta.5-C5Me4R)2(.mu.-H)2}2Mg], where R = Ph (1) or 4-fluorophenyl (FPh, 2), the dinuclear [Ti(.eta.5-C5Me4Ph)[.eta.5:.eta.1{Ti:Mg}-C5Me4(o-C6H4)](.mu.-H)2Mg(THF)2] (3) and [Ti(.eta.5-C5Me4Ph)2(.mu.-H)2MgC(Me)=CHMe] (4) complexes, and the [{Ti(.eta.5-C5Me4Ph)2(.eta.1-CCSiMe3)2}-{MgCl(THF)}+] (5) tweezer complex initiated the dimerization of (trimethylsilyl)ethyne (TMSE) or 1-hexyne (HXNY) to exclusively head-to-tail dimers at 60 C with the turnover number ranging 300 - 500 mol of the alkyne per one mol of the Ti complex. In contrast, all of them were inactive in the dimerization of tert.-butylethyne (TBUE). Monitoring of reactions of the 1 - 5 complexes with the alkynes by electron spin resonance (ESR) method revealed a decay of the initial complexes 1 - 5 in the dimerizing systems with TMSE and HXYN or a conversion of complexes 3,4 and 5.
