A catalytic hypervalent iodine oxidation of p-dialkoxybenzenes using 4-iodophenoxyacetic acid (1) and 2KHSO5 x KHSO4 x K2SO4 (Oxone) was developed. Reaction of p-dialkoxybenzenes (2) with a catalytic amount of 1 in the presence of Oxone as a co-oxidant in 2,2,2-trifluoroethanol-water (1 : 2) gave the corresponding p-quinones (3) in excellent yields without purification. This procedure was applied to
开发了使用4-碘苯氧基乙酸(1)和2KHSO5 x KHSO4 x K2SO4(Oxone)对对二烷氧基苯进行催化的高价碘氧化。在作为辅助氧化剂的Oxone存在下,对二烷氧基苯(2)与催化量为1的反应在2,2,2-三氟乙醇-水(1:2)中反应,生成了相应的对苯醌(3)无需纯化即可产生。该程序用于合成德国小Bl Blattella germanica的性信息素blattellaquinone(9)。
