eosin Y catalyzed aerobic oxidative α-C(sp3)–H thiocyanation of tertiary amines is reported. The reaction proceeds through visible-light-induced in situ generation of the iminium ion followed by attack of −SCN nucleophile. This is the first example of visible-light-initiated formation of C(sp3)–S bond employing organo-photoredox catalysis. Mild reaction conditions and use of air and visible light as the
可见光诱导的曙红Y催化叔胺的需氧氧化α-C(sp 3)–H硫氰化。该反应通过可见光诱导的原位生成亚胺离子,随后的攻击- SCN亲核体。这是利用有机光氧化还原催化可见光引发的C(sp 3)-S键形成的第一个例子。该方案的主要特点是温和的反应条件以及在室温下使用空气和可见光作为最绿色和可持续的试剂。
