Abstract

[reaction: see text] Efficient photorelease (Phi = 0.7) of carboxylic acids is achieved with a covalently linked mediator (benzophenone) protecting group (N-alkyl-4-picolinium ester) molecule. The mechanism involves initial photoreduction of the mediator, followed by rapid electron transfer to the protecting group.

摘要

[反应：见正文] 羧酸通过共价连接的介导剂（二苯甲酮）保护基团（N-烷基-4-吡啶鎓酯）分子实现高效光释放（Φ = 0.7）。其机制包括介导剂的初始光还原，随后快速电子转移至保护基团。
