Abstract
Graphitic-C3N4 is shown for the first time to catalyse photoacetalization of aldehydes/ketones with alcohols to acetals in high yields using visible light under ambient conditions; transient charge separation over the material is effective to catalyse the reaction in the absence of Lewis or Brønsted acids, giving a new green alternative catalyst.
摘要
首次表明，石墨相氮化碳在环境条件下利用可见光可催化醛/酮与醇高效光缩醛化生成缩醛；在无路易斯酸或布朗斯特酸的情况下，该材料上的瞬态电荷分离能有效催化反应，从而提供了一种新型绿色替代催化剂。
