Conversion of nucleophilic halides to electrophilic halides: efficient and selective halogenation of azinones, amides, and carbonyl compounds using metal halide/lead tetraacetate was written by Kim, Jeum-Jong;Kweon, Deok-Heon;Cho, Su-Dong;Kim, Ho-Kyun;Lee, Sang-Gyeong;Yoon, Yong-Jin. And the article was included in Synlett in 2006.COA of Formula: C7H4ClNO3S This article mentions the following:
AlCl3/Pb(OAc)4 and ZnBr2/Pb(OAc)4 are efficient electrophilic N- and α-C-halogenating agents. A variety of azinones, amides, and carbonyl compounds were chemoselectively and regioselectively N- or α-C-halogenated in good to excellent yield using AlCl3/Pb(OAc)4 or ZnBr2/Pb(OAc)4 in acetonitrile. In the experiment, the researchers used many compounds, for example, 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0COA of Formula: C7H4ClNO3S).
2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.COA of Formula: C7H4ClNO3S
