the major product together with 3-alkoxyphthalides. 3-Alkoxycarbonylphthalides may be derived from the reaction between alcohols and the spirooxiranone intermediate, generated photochemically by cleavage of the bond between two carbonyl groups of indane-1,2,3-trione via a cyclobutenone biradical derivative.
在脱气的醇溶液中辐照茚满-1,2,3-三酮可得到 3-烷氧基羰基苯酞和 3-烷氧基苯酞作为主要产物。3-烷氧基羰基邻苯二甲醚可以衍生自醇和螺环酮中间体之间的反应,通过环丁烯酮双自由基衍生物裂解茚满-1,2,3-三酮的两个羰基之间的键以光化学方式产生。
