Para-substituted benzene compounds, p-XC6H4X′ (X CF3C(O) and X′ CH3, CO2H, C(O)CF3, C(O)CH3, C(O)H and SH) have been prepared via sequential metal-halogen exchange reactions between p-BrC6H4Br and n-C4H9Li and the appropriate electrophiles. Low reaction temperature is critical to stabilization of the various intermediates. The CF3 group has a pronounced effect on providing stability to the lithium
对位取代的苯化合物p -XC 6 H 4 X'(XCF 3 C(O)和X'CH 3,CO 2 H,C(O)CF 3,C(O)CH 3,C( O)H和SH)是通过在p -BrC 6 H 4 Br和nC 4 H 9 Li与适当的亲电子试剂之间进行连续的金属-卤素交换反应而制备的。低的反应温度对于稳定各种中间体至关重要。CF 3基团在为锂半缩酮中间体提供稳定性方面具有显著作用。

enantioselectivity of the bakers' yeastreduction of p-substituted trifluoroacetylbenzene derivatives could be improved by the introduction of some functional groups at the para-position to give the corresponding (R)-trifluoromethyl-substituted benzylic alcohols in high chemical and optical yields. The optically active alcohols obtained were readily converted into optically pure forms by recrystallization

providing an efficient method for the synthesis of poly(arylene vinylene)s (PAVs). This method affords PAVs bearing E-vinylene units predominantly. It can also introduce a CF3 group on each vinylene carbon atom in the polymer main chain. The polymerization has a broad scope and the resultant polymers exhibit interesting optical properties and good thermal stabilities.
