Abstract

[PtBr(PEt₃)₃]BF₄ (1) reacts with an excess of dimethyl{4-(trifluoromethyl)phenyl}silanol in the presence of Ag₂O and 4 Å molecular sieves at 60°C to afford trans-Pt(C₆H₄CF₃-4)₂ (PEt₃)₂ (2). The reaction without molecular sieves and that with addition of a small amount of water give a mixture of 2 and [Pt₂(μ-OH)₂-(PEt₃)₄] (BF₄)₂ (3). The organic products of the reaction are composed of ArSiMe₂-O-(SiMe₂-O)_n- SiMe₂Ar (Ar = C₆H₄CF₃-4, n = 0, 1, 2) and cyclooligodimethylsiloxanes in lesser amounts. The obtained complexes were characterized by NMR spectroscopy and X-ray crystallography.
