Structural diversity in nonafluoromesityl chemistry

Abstract

Several new compounds containing the nonafluoromesityl substituent [2,4,6-tris(trifluoromethyl)phenyl, abbreviated as R_F] have been prepared and structurally characterized. Solid state structures are reported for C₅Me₅P(Cl)R_F (1), Sn(SeR_F)₄ (3), Te(R_F)₂ (4) and (AgR_F)₄ (5). 1 and 4 crystallize in space group P2₁/c, 3 in space group P, and 5 in space group I4₁/a. While 1 and 3 are monomeric in the solid state, the telluride 4 is dimerized via Te···F secondary bonds and 5 adopts a tetrameric structure containing a central Ag₄ ring. Furthermore the preparation of C₅Me₅P(H)R_F (2) is described.
