Competitive cyclization of singlet and triplet nitrenes. Part 7. Reaction paths of 2-azidophenyl benzothienyl sulfides was written by Hawkins, David G.;Meth-Cohn, Otto;Suschitzky, Hans. And the article was included in Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) in 1979.Product Details of 10243-15-9 This article mentions the following:
Thermal decomposition of I (R = Me) and II gave III and IV, resp., via spirobenzothiazoline intermediates. 2-(2,3-Dihydro-3-benzo[b]thienyl)benzothiazole and 2-(3-benzo[b]thienyl)benzothiazole were also obtained from the thermal decomposition of I (R = Me). Similar thermolysis of I (R = H) resulted in polymer formation only, indicating the necessity of the Me substituent. 2-Azidophenyl 3-(2,5-dimethylthienyl) sulfide, however, gave 2-methylbenzothiazole. These various reaction paths are rationalized by comparison with those of the related thienyl sulfides. In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Product Details of 10243-15-9).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.Product Details of 10243-15-9
