《The synthesis of sulfonated 4H-3,1-benzoxazines via an electro-chemical radical cascade cyclization》 was published in Chemical Communications (Cambridge, United Kingdom) in 2020. These research results belong to He, Tian-Jun; Zhong, Wei-Qiang; Huang, Jing-Mei. Application In Synthesis of 4-Chlorobenzenesulfonyl chloride The article mentions the following:
A new route for the synthesis of sulfonated 4H-3,1-benzoxazines I (R1 = H, Me, C6H5; R2 = H, 4-Me, 4-F, etc.; R3 = C6H5, 4-FC6H4, 2-furyl, etc.) has been accomplished by electrochem. radical cascade cyclizations of styrenyl amides with sulfonylhydrazines. This process demonstrates a wide substrate scope with diverse functional group compatibility under metal- and external oxidant-free conditions at ambient temperature4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Application In Synthesis of 4-Chlorobenzenesulfonyl chloride) was used in this study.
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. Application In Synthesis of 4-Chlorobenzenesulfonyl chloride 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.
