《A general and practical sulfonylation of benzylic ammonium salts with sulfonyl hydrazides for the synthesis of sulfones》 was published in Tetrahedron Letters in 2020. These research results belong to Zhu, Haibo; Zhang, Yingying; Liu, Yishuai; Yang, Liu; Xie, Zongbo; Jiang, Guofang; Le, Zhang-Gao. Recommanded Product: 4-Chlorobenzenesulfonyl chloride The article mentions the following:
A practical and efficient approach adopting transition-metal-free cross-coupling of sulfonyl hydrazides with benzyl ammonium salts was developed to synthesize benzyl sulfones using Cs2CO3 as base under mild conditions. The protocol employed stable and easy to handle coupling partners, and was endowed with good substrate compatibility, leading to functional benzyl sulfones in good yields. In the experiment, the researchers used many compounds, for example, 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Recommanded Product: 4-Chlorobenzenesulfonyl chloride)
4-Chlorobenzenesulfonyl chloride(cas: 98-60-2) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. Recommanded Product: 4-Chlorobenzenesulfonyl chloride However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.
