A metal-free visible light photoredox-catalyzed synthesis of N-unsubstituted enaminosulfones from vinyl azides and sodium sulfinates in moderate to high yields were described. The reaction proceeded in ethanol and used Eosin Y as a readily available photocatalyst in combination with nitrobenzene as an electron shuttle. Took into account the number of steps involved (generation of the sulfonyl radical, its addition to the double bond, elimination of mol. nitrogen with formation of an iminyl radical, followed by its reduction and protonation) as well as the number of redox-active reaction partners involved, the selectivity of the process was quite impressive. In the experimental materials used by the author, we found 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Product Details of 98-60-2)
4-Chlorobenzenesulfonyl chloride(cas: 98-60-2) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. Product Details of 98-60-2 However, the extent of chlorination is difficult to control. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.
