The 1H and 13C NMR spectra of methyl (E)‐2,3,‐diphenylprop‐2‐enoate and methyl (E)‐2‐(2‐phenylethenyl) benzoate resulting from the electrocyclic ring opening of benzocyclobutenone starting materials have been assigned. A combination of direct detection 2D NMR techniques, COSY, HETCOR and FLOCK, provided the assignments of the 1H and 13C resonances.
(E)-2,3,-二苯基丙-2-烯酸甲酯和 (E)-2-(2-苯基乙烯基)苯甲酸甲酯的 1H 和 13C NMR 谱已被指定为由苯并环丁烯酮起始材料的电环开环产生的。直接检测 2D NMR 技术、COSY、HETCOR 和 FLOCK 的组合提供了 1H 和 13C 共振的分配。
