In the solvolysis of 4-alkoxy-5-methyl-o-benzoquinone N-arylsulphonylimines (1a) and (1b)(NaOH-MeOH–H2O), the regiospecific attack of MeO– occurs initially on the carbon atom substituted by the alkoxy-group to produce the p-benzoquinone monoacetals (3a) and (3b), respectively.
在4 -烷氧基-5-甲基-溶剂解ø醌Ñ -arylsulphonylimines(1A)和(1B)氢氧化钠(NaOH-MeOH中-H 2 O),的MeO的区域专一性攻击-最初在碳原子上发生由取代的烷氧基分别生成对-苯醌单缩醛(3a)和(3b)。
