- Аннотация: Reaction of isomeric mixture of 1,2,3,4-tetramethyl-5-(trifluoromethyl)cyclopentadiene with Zeise's salt dimer gave the only isomer [Pt{eta (4)-C5Me4(CF3)H}Cl-2] (1) bearing CF3 group exo to sp(3) carbon atom in a high yield. An attempt to prepare 1 by reaction of K2PtCl4 with C5Me4(CF3)H using hydrochloric solution of tin dichloride as a catalyst unexpectedly resulted in a formation of [Pt(eta (4)-C5Me4H2)Cl-2] (2). The X-ray structure of compound 2 is presented. Reactions of 1 with AgBF4 in the presence of three different cyclopentadienes C5R41(R-2)H (R-1 = R-2 = H; R-1 = R-2 = Me; R-1 = Me, R-2 = CF3) were studied. Crystal structure of complex [Pt{eta (4)-C5Me4(CF3)H}(eta (5)-C5H5)]PF6 (3) resulted from the reaction with cyclopentadiene was determined. When C5Me4(CF3)H is used the reaction yields [Pt{eta (4)-C5Me4(CF3)H}{eta (5)-C5Me4(CF3)}]BF4 (4) unstable in solutions. Reaction with pentamethylcyclopentadiene led to complex [Pt(eta (4)-C5Me5H)(eta (5)-C5Me5)]BF4 (5) and no complexes with CF, containing ligands were obtained.
