In 2019,Organic & Biomolecular Chemistry included an article by Wang, Qiao-Lin; Zhang, Wen-Zheng; Zhou, Quan; Zhou, Cong-Shan; Xiong, Bi-Quan; Tang, Ke-Wen; Liu, Yu. Formula: C6H4Cl2O2S. The article was titled 《Visible-light-mediated difunctionalization of vinylcyclopropanes for the synthesis of 1-sulfonylmethyl-3,4-dihydronaphthalenes》. The information in the text is summarized as follows:
An efficient method for visible-light-mediated sulfonylation/arylation of the C-C σ-bond in vinylcyclopropanes with sulfonyl chlorides to synthesize 1-sulfonylmethyl-substituted 3,4-dihydronaphalenes was developed. A radical-type pathway was proved in this transformation. This difunctionalization procedure showed a series of advantages, such as the use of com. and easily available sulfonyl chlorides, mild conditions and eco-friendly energy. In the experimental materials used by the author, we found 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Formula: C6H4Cl2O2S)
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. 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.Formula: C6H4Cl2O2S
