  可见光光氧化还原催化生成的烷氧基进行醇醚化

  摘要：

  描述了一种机械发散的方法，该方法使用市售的高价碘（III）试剂，可从1°，2°和3°醇生成烷氧基，并允许它们用于C（sp 3）–H和C的官能化（sp 2）–H键。这种可见光的光氧化还原催化反应通过1,5 / 6-氢原子转移生成烷基醚，或通过1,5-加成生成芳基醚。这种温和的方法为乙缩醛，原酸酯，四氢呋喃和苯并二氢吡喃的合成提供了实用的策略。

  The sulfonium salt does not contain a toxic metal and exhibits higher cationic polymerization performance and crosslinking performance than a tetrakis(pentafluorophenyl)borate salt. The heat- or photo-acid generator contains the sulfonium salt. The sulfonium salt is formed of a sulfonium cation selected from a group represented by general formulas (1), (9), (10) and (11) described below and a gallate anion represented by formula (a). The heat- or photo-acid generator contains the sulfonium salt. The heat- or energy ray-curable composition contains the acid generator and a cationically polymerizable compound. A cured product can be obtained by curing the same.
