This Letter describes the method for C-devinylation of aromatic systems for the first time. Vinylbenzenes on refluxing with trifluoroacetic acid produced corresponding devinylated products in excellent yields. Furthermore, 2,4,6-trimethoxy vinylbenzenes on treatment with hexamethylene tetraamine and trifluoroacetic acid exclusively produced 1,3-diformyl 2,4,6-trimethoxy benzene via tandem devinylation
这封信首次描述了芳族系统C-脱癸基化的方法。与三氟乙酸一起回流的乙烯基苯以优异的产率产生了相应的去乙烯基化产物。此外,用六亚甲基四胺和三氟乙酸处理的2,4,6-三甲氧基乙烯基苯通过串联脱甲酰基化和二甲酰基化反应独家生产了1,3-二甲酰基2,4,6-三甲氧基苯。可以使用多种脂族乙烯基,但反应限于1,3,5-三甲氧基苯。
