halogenating agents. It is now shown that simple inorganic halide salts can be used for halogenation of N-hydroxyphthalimide-activated carboxylic acids under visible-light photoredox catalysis. Halodecarboxylation proceeded with LiBr and LiCl, and the generality of the conditions was demonstrated by extension to decarboxylative thiocyanation with KSCN.
脱羧卤化通常需要
化学计量的强氧化剂或亲电卤化剂。现在表明,简单的无机卤化物盐可用于在可见光光氧化还原催化下卤化N-羟基邻苯二甲
酰亚胺活化的
羧酸。用 LiBr 和 LiCl 进行卤代脱羧反应,并通过扩展到用 KSCN 进行脱羧
硫氰化反应来证明该条件的通用性。
