Rastogi, Rashmi et al. published their research in Indian Journal of Chemistry, Section B: Organic Chemistry Including Medicinal Chemistry in 1982 |CAS: 5709-67-1

On May 31, 1982, Rastogi, Rashmi; Sharma, Satyavan published an article.Computed Properties of 5709-67-1 The title of the article was Synthesis of 2-substituted benzofurans as potential anthelmintics. And the article contained the following:

Thirteen title compounds, e.g. I (R = 2-O2NC6H4, 2-H2NC6H4, 2-benzimidazolyl) and II (X = NH, S), were prepared starting from 2-benzofurancarbonyl chloride. The title compounds were tested as anthelmintics, bactericides, and fungicides and found to be inactive. The experimental process involved the reaction of 2-Nitro-1H-benzo[d]imidazole(cas: 5709-67-1).Computed Properties of 5709-67-1

The Article related to benzofuran substituted preparation anthelmintic, bactericide substituted benzofuran, fungicide substituted benzofuran, benzimidazolylbenzofuran, benzothiazolylbenzofuran, Heterocyclic Compounds (One Hetero Atom): Areno- and Diarenofurans and other aspects.Computed Properties of 5709-67-1
