visible-light-induced radical cascade cyclization of 2-isocyanoaryl thioethers for the synthesis of 2-CF2/CF3-containing benzothiazoles has been developed. Sodium sulfite can participate in the photocatalytic cycle as a reductant that efficiently transforms Ir4+ into Ir3+ to promote the fluoroalkylation under mild reaction conditions.
已经开发了可见光诱导的2-异
氰基芳基
硫醚的自由基级联环化反应,用于合成含2-CF 2 / CF 3的
苯并噻唑。
亚硫酸钠可作为还原剂参与光催化循环,该还原剂可在温和的反应条件下有效地将Ir 4+转化为Ir 3+从而促进氟烷基化。
