A method of alkylation and acylation of trinitrobenzene employing the oxidation of anionic σ-complexes generated from organosilicon reagents in the presence of KF/18-crown-6 ether is described. The method enables the introduction of alkyl and acyl substituents (R = O, CH2COEt, CH2COOMe(Et), COMe, COPh, CH2Ph, CH2=CHCH2 (All), CCPh) into 1,3,5-trinitrobenzene, 1,3,5-Tris(trifluoromethylsulfonyl)benzene
描述了一种三硝基苯的烷基化和酰化的方法,该方法利用在KF / 18-冠-6醚存在下由有机硅试剂生成的阴离子σ-络合物的氧化作用。该方法能够将烷基和酰基取代基(R = O,CH 2 COEt,CH 2 COOMe(Et),COMe,COPh,CH 2 Ph,CH 2 = CHCH 2(All),CCPh)引入1,在所述条件下的3,5-三硝基苯,1,3,5-三(三氟甲基磺酰基)苯仅与环己酮烯醇三甲基甲硅烷基醚反应。
