《Copper-catalyzed cascade bicyclization of o-alkenylphenyl isothiocyanates with sodium azide leading to 5H-benzo[d]tetrazolo[5,1-b][1,3]thiazines》 was published in Youji Huaxue in 2020. These research results belong to Zhang, Yahui; Liu, Yang; Miao, Jiankang; Hao, Wenyan. Electric Literature of C6H5ClIN The article mentions the following:
A simple and efficient method for the preparation of 5H-benzo[d]tetrazolo[5,1-b][1,3]thiazines has been developed. The transformation involved the copper (I)-catalyzed cascade bicyclization of o-alkenylphenyl isothiocyanates with sodium azide to afford corresponding products in moderate to good yields. This present strategy provides an effective way to construct small mol. N-, and S-heterocycles. After reading the article, we found that the author used 4-Chloro-2-iodoaniline(cas: 63069-48-7Electric Literature of C6H5ClIN)
4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. Aniline, ethanolamines, and several other amines are major industrial commodities used in making rubber, dyes, pharmaceuticals, and synthetic resins and fibres and for a host of other applications. Most of the numerous methods for the preparation of amines may be broadly divided into two groups: (1) chemical reduction (replacement of oxygen with hydrogen atoms in the molecule) of members of several other classes of organic nitrogen compounds and (2) reactions of ammonia or amines with organic compounds.Electric Literature of C6H5ClIN
