A novel polymer was synthesized by copolymerization of styrene monomer bearing dicyanoketene acetal functionality and ethylene glycol dimethacrylate, and used successfully as a recyclable π-acid catalyst in monothioacetalization of aromatic, aliphatic, acyclic, and cyclic acetals with thiophenol and phenylthiotrimethylsilane.
通过带有双氰基乙缩醛官能团的苯乙烯单体与乙二醇二甲基丙烯酸酯的共聚反应合成了一种新型聚合物,并成功地用作芳香族,脂肪族,无环和环状缩醛与硫代苯酚和苯基硫代三甲基硅烷的单硫缩醛化反应中的可循环使用的π-酸催化剂。
