dioxetane bearing a 3-(1-cyanoethenyl)phenyl group (1) was synthesized. Michael addition of an anion of malonate (3a,b) to a dioxetane (1) substituted with a 3-(1-cyanoethenyl)phenyl moiety took place to give an intermediary dioxetane bearing a benzylic anion, which decomposes rapidly with accompanying emission of crimson light. When an anion of chloromalonate (3c) was used as a base, intramolecular cyclopropanation
合成具有3-(1-氰基乙烯基)苯基(1)的热稳定的二氧杂环丁烷。发生了将丙二酸根阴离子(3a,b)迈克尔加成到被3-(1-氰基乙烯基)苯基部分取代的二氧杂环丁烷(1)的过程,从而得到了带有苄基阴离子的中间体二氧杂环丁烷,该中间体迅速分解并伴随着深红色的散发。光。当氯丙二酸根(3c)的阴离子用作碱时,3c的分子内环丙烷化与迈克尔加成反应引起的化学发光分解同时发生。
