Resumo

Reactions of [ν5-C5H4P(C6H5 )22TiCl2] with HSR in the presence of Et3N gave the new compounds ν5-C5H4P(C6H5) 22Ti(SR)2] (R = CH2C6H5 (1), C6H5 (2), CH2CH3 (3), C6F5 (4) and [ν5-C5H4P(C6H52)2TiCl(SC6H11)] (5). The complex [ν5C5H4P(C6H5) 2)2Ti(SC6F5)2] can be prepared in higher yield by reaction of TISC6F5 with [ν5-C5H4P(C6H5 )22TiCl2] in toluene. These compounds are of interest as metalloligands to form bimetallic and trimetallic species. The treatment of [ν5-C5H4P(C6H5 )2TiCl2] or [ν5-C5H4P(C6H5 )2Ti(SC6H5)2] with cis-[M(C6F5)2(THF)2] gave the new heterobimetallic complexes [Cl2Tiμ-C5H4P(C6H5)22M(C6F5)2] [M=Pt (6) or Pd (7)] and [(C6H5S)2Tiμ-C5H4P(C6H5)22Pt(C6 F5)2] (8). In all cases the THF of the cis-[M(C6F5) (THF)2] was easily replaced by the phosphine rather than chloride or thiolate. The compounds have been characterized by 1H, 31P and 19F NMR spectroscopies and FAB mass spectrometry. © 1995.
