An efficient, metal-free protocol for the three-component sulfonylative pyridylation of alkenes via organic-photoredox catalysis was described. Metal-free process enabled the direct and selective installation of sulfonyl and heteroaryl motifs and tolerated a wide array of functional groups as well as complex mol. scaffolds, which complemented previous methods and was of great interest in pharmaceutical research. In the experiment, the researchers used many compounds, for example, 4-Cyanopyridine(cas: 100-48-1Application of 100-48-1)
4-Cyanopyridine(cas: 100-48-1) 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. Application of 100-48-1
