visible‐light photoredox catalysis. A wide range of readily available mono‐, di‐, and trifluoromethyl heteroaryl sulfones can thus be used as efficient radical fluoroalkylation reagents under mild conditions. This method not only describes a new synthetic application of fluorinated sulfones, but also provides a new route to fluoroalkyl radicals.
可见光光氧化还原催化作用使异氰酸酯与氟化砜发生自由基氟烷基化。因此,在温和的条件下,可以使用各种容易获得的单,二和三氟甲基杂芳基砜作为有效的自由基氟代烷基化试剂。该方法不仅描述了氟化砜的新合成应用,而且为氟代烷基自由基的制备提供了新途径。
