Hazard Information | Back Directory | [Uses]
1,3,5-tris(trifluoromethyl)benzene was used as a starting material in the synthesis of bis(2,4,6-tris(trifluoromethyl)phenyl)chloropnictines. It may be used as a starting material in the synthesis of 2,4,6-tris(trifluoromethyl)benzoic acid by reacting with n-butyllithium and carbon dioxide and in the synthesis of lithio derivative, via direct metalation with n-butyllithium. | [General Description]
1,3,5-tris(trifluoromethyl)benzene is a tri-substituted benzene. It has been synthesized by reacting benzene-1,3,5-tricarboxylic acid with SF4. Reports suggest that 1,3,5-tris(trifluoromethyl)benzene is a nonanesthetics and shows convulsant properties. Its vapor absorption spectra and corresponding solution spectra has been investigated. Its reaction with methyl lithium has been analyzed using semiempirical reaction modelling. | [Structure and conformation]
The principal structural parameters rh1(∠h1) determined by GED are (bond lengths in Angstroms and bond angles in degrees with 3σ in parentheses): r(C C)=1.392(4), r(C?C)=1.512(4), r(C?F)av=1.346(2), ∠C–C(CF3)– C=120.9(2), ∠C–C(H)–C=119.1(2), ∠(C–C–F)av=111.6(2). The structure of the carbon ring deviates from a regular hexagon due to the σ-electronegative effect of the CF3 groups. The geometric parameters of the trifluoromethyl groups deviate considerably from regular tetrahedron arrangement[1].
