A photocatalytic active alkyne generation reaction was developed using cyclopropenone as a starting reagent. Visible light-responsive photocatalysts induced cyclopropenone decarbonylation. The resulting highly reactive alkyne could be used directly, without isolation, for further reactions, such as in a dehydration condensation reaction and alkyne–azide click chemistry.
使用环丙烯酮作为起始试剂开发了光催化活性炔烃生成反应。可见光响应性光催化剂诱导环丙烯酮脱羰。由此产生的高反应性炔烃可不经分离直接用于进一步的反应,例如在脱水缩合反应和炔烃-叠氮化click点击化学中。
