A new photocatalytic three-component annulation of 2-alkynylaryldiazonium tetrafluoroborates with γ-hydroxyl terminal alkynes and sodium metabisulfite is reported using fac-Ir(ppy)3 as the photocatalyst for the first time and used to produce a series of (Z)-thiochromene 1,1-dioxides I (R1 = H, 6-Me, 6-Cl, etc.; R2 = C6H5, 4-MeC6H4, 4-ClC6H4, etc.; R3 = H, 4-Me; R4 = Et, n-Bu, C6H5, etc.) bearing an exocyclic double bond with moderate to good yields in a highly stereoselective manner. A wide variety of easily available substrates with substituent diversity could successfully participate in this photocatalysis with good functional group tolerance. The results came from multiple reactions, including the reaction of 4-Chloro-2-iodoaniline(cas: 63069-48-7Application of 63069-48-7)
4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).Application of 63069-48-7
