Decatungstate is a potent photocatalyst for hydrogen atom transfer (HAT) but faces degradation issues when using a typical tetra-n-butylammonium salt. Herein, we employed tetraphenylphosphonium as a countercation to yield a highly durable and efficient HAT photocatalyst, enabling α-oxygenation of amides to their corresponding imides using O₂ as an oxidant.

使用高度耐用的十钨酸盐四苯基鏻盐将酰胺光催化有氧 α-氧化成酰亚胺

十钨酸盐是一种有效的氢原子转移（HAT）光催化剂，但在使用典型的四正丁基铵盐时面临降解问题。在此，我们使用四苯基鏻作为抗衡阳离子来产生高度耐用且高效的HAT光催化剂，能够使用O ₂作为氧化剂将酰胺α-氧化成其相应的酰亚胺。
