A metal-free approach for the C4-arylation of 4-substituted-pyrazolin-5-ones I (R = H, H2CHC:CH2, H2CC6H5, 4-F-C6H4CH2, etc.; R1 = CH3, C6H5; R2 = C6H5, 4-H3CC6H4, 4-F3CC6H4) with diaryliodonium salts was developed. The reaction proceeded smoothly at room temperature in the presence of DMAP (4-dimethylaminopyridine). As a result, a wide range of desired multi-substituted pyrazolin-5-one derivatives II were obtained in good to excellent yields (20-98%). This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3SDS of cas: 139139-80-3).
Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3) belongs to iodide derivatives. Indole, also called Benzopyrrole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.SDS of cas: 139139-80-3
