Pd-catalyzed dehydrogenative annulation approach for the efficient synthesis of phenanthridinones was written by Li, Xinyao;Pan, Jun;Song, Song;Jiao, Ning. And the article was included in Chemical Science in 2016.SDS of cas: 36748-88-6 This article mentions the following:
A novel Pd-catalyzed intermol. dehydrogenative annulation of aryl iodides and aryl carbamic chlorides for the efficient synthesis of phenanthridinone derivatives was developed. Simple aryl iodides and carbamic chlorides readily made from various anilines, a broad substrate scope with hetero/polycycles, as well as high-value products, made this direct dehydrogenative annulation approach very practical and attractive. In the experiment, the researchers used many compounds, for example, 3-Iodobenzo[b]thiophene (cas: 36748-88-6SDS of cas: 36748-88-6).
3-Iodobenzo[b]thiophene (cas: 36748-88-6) belongs to iodide derivatives. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.SDS of cas: 36748-88-6
