Ni-catalyzed aryl sulfide synthesis through an aryl exchange reaction between aryl sulfides and a variety of aryl electrophiles was developed. By using 2-pyridyl sulfide as a sulfide donor, this reaction achieved the synthesis of aryl sulfides without using odorous and toxic thiols. The use of a Ni/dcypt catalyst capable of cleaving and forming aryl–S bonds was important for the aryl exchange reaction
通过芳基硫化物与多种芳基亲电试剂之间的芳基交换反应,开发了镍催化芳基硫化物合成。通过使用2-吡啶基硫醚作为硫化物供体,该反应实现了芳基硫化物的合成,而无需使用有臭味和有毒的硫醇。使用能够裂解和形成芳基-S 键的 Ni/dcypt 催化剂对于 2-吡啶基硫化物和芳基亲电试剂之间的芳基交换反应很重要,包括芳族酯、芳醇衍生物和芳基卤化物。机理研究表明,Ni/dcypt 可以同时进行芳基硫化物和芳族酯的氧化加成,然后在生成的芳基-Ni-SR 和芳基-Ni-OAr 物种之间进行配体交换,以提供芳基交换化合物。
