Poly(3,4‐dimethyl‐5‐vinylthiazolium) was synthesized from 3,4‐dimethyl‐5‐vinylthiazole through free radical polymerization and was examined as polymer precatalysts in the presence of 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) for the thioesterification of aldehydes with thiols. The poly(5‐vinylthiazolium)/DBU had excellent catalytic activity and could be reused 10 times without a considerable loss of
聚(3,4-二甲基-5-乙烯基噻唑鎓)是通过自由基聚合从3,4-二甲基-5-乙烯基噻唑合成的,并在存在1,8-二氮杂双环[5.4.0]十一碳的情况下作为聚合物前催化剂进行了研究。 7-烯(DBU)用于醛与硫醇的硫酯化反应。聚(5-乙烯基噻唑鎓)/ DBU具有出色的催化活性,可以重复使用10次,而活性没有明显损失。
