6-methylidenecyclohexa-2,4-diene-1-carboxylateunder flash vacuum pyrolysis (f.v.p.) conditions has been obtained by a studyof the f.v.p. products obtained from methyl1-methyl-6-methylidenecyclohexa-2,4-diene-1-carboxylate and methyl2,2-dimethylbut-3-enoate. A significant product in each case arises from areaction involving decarbonylation and transfer of a methoxy group to C 4(but-3-enoate numbering)
通过对从甲基 1-甲基-6-获得的 fvp 产品的研究,获得了对 Khalafy 和 Prager1 的建议,即 6-亚甲基环己基-2,4-二烯-1-羧酸盐在闪蒸真空热解 (fvp) 条件下的亲变重排的建议。亚甲基环六-2,4-二烯-1-羧酸和2,2-二甲基丁-3-烯酸甲酯。在每种情况下,重要的产物来自涉及脱羰基和甲氧基转移到 C 4(丁-3-烯酸酯编号)的反应。
