Huo, Yong-Wang; Qi, Xinxin; Wu, Xiao-Feng published an article in 2022. The article was titled 《Nickel-Catalyzed Carbonylative Synthesis of α,β-Unsaturated Thioesters from Vinyl Triflates and Arylsulfonyl Chlorides》, and you may find the article in Organic Letters.Electric Literature of C6H4Cl2O2S The information in the text is summarized as follows:
A straightforward and efficient synthesis of α,β-unsaturated thioesters RC(O)SR1 [R = cyclopenten-1-yl, cyclohexen-1-yl, 3,4-dihydronaphthalen-1-yl, etc.; R1 = 4-MeC6H4, 4-FC6H4, 4-MeOC6H4, etc.] had been developed via a nickel-catalyzed thiocarbonylation reaction of vinyl triflates with arylsulfonyl chlorides. With Mo(CO)6 as both CO source and reductant, a variety of α,β-unsaturated thioesters were obtained in moderate to good yields with very good functional group compatibility. It was noteworthy that the present method was the first example on nickel-catalyzed carbonylative synthesis of α,β-unsaturated thioesters by using arylsulfonyl chlorides as the coupling partner. In the part of experimental materials, we found many familiar compounds, such as 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Electric Literature of 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. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Electric Literature of C6H4Cl2O2S
