发展了一种有效的可见光诱导的杂芳烃与脂肪醇的直接交叉脱氢偶联. 该反应在水溶液中由过硫酸盐引发, 不需要使用化学计量酸来活化杂环. 通过氢原子转移(HAT)从醇瞬时生成的α-羟烷基自由基与一系列杂芳烃发生Minisci反应. 该方法具有无需光催化剂、溶剂绿色环保、反应条件温和、起始材料容易获得和官能团耐受性广泛等优点.

An efficient visible light-induced direct cross-dehydrogenative coupling of heteroarenes with aliphatic alcohols in aqueous solution at ambient temperature was developed. The reaction is initiated by persulfate salts and does not require the use of stoichiometric acid for activation of the heterocycle. α-Hydroxyalkyl radicals transiently generated from alcohols via hydrogen atom transfer (HAT) undergo Minisci-type reactions with a range of heteroarenes. This protocol was highlighted by photocatalyst-free, green solvent, mild conditions, readily available starting materials, and wide functional group tolerance.

Key words: alcohol, cross-dehydrogenative coupling, heteroarene, hydroxyalkylation, visible light-induction
