developed. The reaction afforded a range of hydrogenated products and sulfonated oxindoles in high yields under external photocatalyst‐free, oxidant‐ and reductant‐free conditions. Mechanistic investigations suggested this transformation is driven by the photochemical activity of hydrogen bond donor‐acceptor complex, generated from the substrates of arylsulfinic acids and C6‐(vinyl sulfone)phenanthridines
已经开发出用于烯烃的氢化和芳基磺酰化的有效的光诱导策略。在无外部光催化剂,无氧化剂和无还原剂的条件下,该反应可提供高产率的一系列氢化产物和磺化羟吲哚。机理研究表明,这种转变是由氢键供体-受体配合物的光化学活性驱动的,该配合物是通过氢键相互作用从芳基亚磺酸和C6-(乙烯基砜)菲啶或N-芳基丙烯酰胺的底物产生的。
