Ortho-quinoid vinylketenes 2 have been generated through flash photolysis of benzocyclobutenones 1. A kinetic study of intermolecular addition reactions of 2 competing with the recyclization 2 → 1 reveals strikingly different substituent effects for the addition of methanol and of dienophiles.
通过苯并环丁烯酮1的快速光解已生成了邻醌类乙烯酮2。分子间加成反应2与环化2→竞争的动力学研究表明,添加甲醇和亲二烯体的取代基效果显着不同。
