Zhang, Qian et al. published their research in Chemical Communications (Cambridge, United Kingdom) in 2022 | CAS: 2387-23-7

1,3-Dicyclohexylurea (cas: 2387-23-7) belongs to amides. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. Amides are stable compounds. The lower-melting members (such as acetamide) can be readily purified by fractional distillation. Most amides are solids which have low solubilities in water.Electric Literature of C13H24N2O

Visible light-promoted synthesis of ureas and formamides from amines and CO2 was written by Zhang, Qian;Hou, Jing;Huang, Yan;Zhan, Le-wu;Li, Bin-dong. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2022.Electric Literature of C13H24N2O This article mentions the following:

A divergent visible-light-induced Ph3P-promoted method for the synthesis of ureas and formamides from amines and CO2 is reported. Without external additions, a range of ureas could be directly accessed under ambient temperature and pressure. Using triisopropylsilanethiol as the hydrogen source, formamides could be produced. In the experiment, the researchers used many compounds, for example, 1,3-Dicyclohexylurea (cas: 2387-23-7Electric Literature of C13H24N2O).
