intermediates in the production of various useful compounds, including antibacterial, antifungal, anti-ulcer and anti-hypertensive agents. In this paper, we developed a new and ecofriendly nanomagnetic catalyst for the synthesis of diaryl sulfides containing imidazo[1,2-a]pyridine, benzoazole, pyrimidine and oxadiazole scaffolds through C–H bond sulfenylation of imidazopyridines.

二芳基硫醚被认为是生产各种有用化合物的有价值的中间体,包括抗菌剂、抗真菌剂、抗溃疡剂和抗高血压剂。在本文中,我们开发了一种新型环保纳米磁性催化剂,用于通过咪唑并吡啶的C-H键磺基化合成含有咪唑并[1,2-a]吡啶、苯并唑、嘧啶和恶二唑支架的二芳基硫醚。通过将CuI固定在经3-氨基-4-巯基苯甲酸(AMBA)修饰的磁性Fe 3 O 4纳米颗粒表面,成功构建了Fe 3 O 4 @AMBA–CuI纳米催化剂。采用 FT-IR 光谱、SEM、EDX、TEM、XRD、VSM、EDX 元素图和 ICP-OES 技术来表征所制造的 Fe 3 O 4 @AMBA-CuI 纳米催化剂的结构。 Fe 3 O 4 @AMBA–CuI 纳米催化剂的回收次数高达八次,活性没有明显损失; VSM和ICP-OES技术证实了回收催化剂的稳定性和高磁性。 图形概要
