A simple five-step method for preparing the previously unknown 1,2-dihydrocyclobutabenzene-3,6-dicarboxylic acid (XTA) in high yield is presented. All intermediates were crystalline compounds which allowed the preparation to be scaled up without complication. The title compound is of interest as a crosslinkable derivative of the widely used monomer, terephthalic acid (TA).
提出了一种高产率制备以前未知的 1,2-二氢环丁苯-3,6-二甲酸 (XTA) 的简单五步方法。所有中间体都是结晶化合物,这使得制备规模扩大而不会变得复杂。 标题化合物作为广泛使用的单体对苯二甲酸 (TA) 的可交联衍生物而受到关注。
