and α-(trans-2-phenylcyclopropyl)-p-tolylmethyl 3,5-dinitrobenzoates (I-4a, b, II-4a, b) has been synthesized. The relative solvolytic rates of I-4b to I-4a and of II-4b to II-4a in 80% aqueous acetone have been found to be 3.59 and 1.86 respectively at 25 °C. In the presence of 2,6-lutidine, the major products in the solvolysis were homoallylic alcohols.
α-(反式-2-对甲苯基环丙基)苄基和α-(反式-2-苯基环丙基)-对甲苯基甲基3,5-二硝基苯甲酸酯(I-4a, b, II-4a, b)的每个非对映异构体对合成的。已发现在 80% 丙酮水溶液中,I-4b 与 I-4a 和 II-4b 与 II-4a 的相对溶剂分解速率在 25°C 下分别为 3.59 和 1.86。在 2,6-二甲基吡啶存在下,溶剂分解中的主要产物是高烯丙醇。
