Qi, Jie et al. published their research in Journal of Organic Chemistry in 2017 | CAS: 638-02-8

2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Product Details of 638-02-8

And the article was included in Journal of Organic Chemistry in 2017.Product Details of 638-02-8 The following contents are mentioned in the article:

TfOH-catalyzed reactions between 3-diazoindolin-2-imines and electron-rich arenes were disclosed. These metal-free reactions furnished 3-aryl-2-aminoindoles in moderate to excellent yields with the tolerance of a broad range of functional groups. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Product Details of 638-02-8).
