The isomeric phenylcamphoric acids, m.p. 140 and 117° prepared by Friedel–Crafts reactions on camphoric anhydride and isolauronolic acid respectively have not the structures previously assigned to them. Both are now shown to be 2,2,3-trimethyl-4-phenylcyclopentanecarboxylic acids which differ only in their configurations about C(1); the hydrogen atoms on C(3) and C(4) of each compound probably have
通过分别在樟脑酸酐和异月桂酸上的Friedel-Crafts反应制备的mp140和117°异构体苯甲酸没有以前指定的结构。现在两者都显示为2,2,3-三甲基-4-苯基环戊烷羧酸,它们的区别仅在于C(1);每个化合物的C(3)和C(4)上的氢原子可能具有顺式关系。
