Poly(3,4-dimethyl-5-vinylthiazolium) iodide was used as a polymer precatalyst in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and phenazine for the oxidative esterification of aldehydes with alcohols. Selective functionalization of OH groups was achieved in the presence of NH groups. The poly(thiazolium) iodide/DBU/phenazine system exhibited excellent catalytic activity and could be reused five times without loss of activity.
聚（3,4-二甲基-5-乙烯基噻唑𬭩）碘化物在 1,8-二氮杂二环[5.4.0]十一碳-7-烯（DBU）和吩嗪的存在下用作聚合物前催化剂，用于醛与醇的氧化酯化。在 NH 基团的存在下，实现了 OH 基团的选择性官能化。聚（噻唑𬭩）碘化物/DBU/吩嗪体系表现出优异的催化活性，可重复使用五次而活性无损失。
