In 2022,Patel, P. N.; Desai, D. H.; Patel, N. C. published an article in Russian Journal of Organic Chemistry. The title of the article was 《Novel Terpyridine Derivatives of Benzothiazole and Copper(II) Complex: Synthesis and Spectral Studies》.Synthetic Route of C7H7NO The author mentioned the following in the article:
Novel terpyridine derivatives of benzothiazole were synthesized by simple multicomponent 1-pot reaction of benzothiazole-2-carbaldehyde, ammonium hydroxide, and isomeric acetyl pyridines with isolated yields of 92-98%. All the prepared derivatives were characterized by NMR, IR, and high-resolution mass spectra. A Cu(II) complex was prepared selectively from the terpyridine derivative obtained from 2-acetylpyridine and was characterized by single-crystal x-ray anal. UV-visible spectra were recorded for all the synthesized compounds In the experiment, the researchers used 4-Acetylpyridine(cas: 1122-54-9Synthetic Route of C7H7NO)
4-Acetylpyridine(cas: 1122-54-9) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Synthetic Route of C7H7NO
