challenge in organic synthesis. In this attractive methodology, we wish to introduce Fe3O4-supported 3-amino-4-mercaptobenzoic acid copper complex (Fe3O4@AMBA-CuI) nanomaterials as a novel and efficient magnetically recoverable catalyst for the preparation of heteroaryl-aryl and di-heteroaryl sulfides with high yields through reaction of heteroaryl halides with aryl or heteroaryl boronic acids and S8
二芳基和二杂芳基硫醚存在于许多药物和重要生物化合物的结构中,并且这些化合物由于重要的生物和药物活性而在药物化学中众所周知。因此,开发新型、环保且高效的催化体系来制备二芳基硫醚和二杂芳基硫醚是有机合成中非常有吸引力且重要的挑战。在这种有吸引力的方法中,我们希望引入 Fe 3 O 4负载的 3-氨基-4-巯基苯甲酸铜配合物 (Fe 3 O 4 @AMBA-CuI) 纳米材料作为一种新型高效的磁可恢复催化剂,用于制备杂芳基-通过杂芳基卤化物与芳基或杂芳基硼酸以及S 8作为硫源在生态友好的条件下反应,高产率地制备芳基和二杂芳基硫醚。该催化体系对于多种杂芳基底物(包括苯并噻唑、苯并恶唑、苯并咪唑、恶二唑、苯并呋喃和咪唑并[1,2- a ]吡啶)非常有效且实用,因为所需的二芳基和二杂芳基硫化物是用高催化速率制备的。产量。可重复使用性实验表明,Fe 3 O 4 @AMBA-CuI纳米催化剂可以磁分离并重

A mild protocol for the synthesis of diaryl and heteroaryl sulfides is described. In a one-pot procedure, thiols are converted to sulfenylchlorides and reacted with arylzinc reagents. This method tolerates functional groups including aryl fluorides and chlorides, ketones, as well as N-heterocycles including pyrimidines, imidazoles, tetrazoles, and oxadiazoles. Two compounds synthesized by this method
