Disclosed herein is a novel radical-mediated intermol. carboarylation of alkenes by cleaving inert C-O bonds. The strategically designed arylbenzothiazolylether diazonium salts are harnessed as dual-function reagents. A vast array of alkenes are proven to be suitable substrates. The benzothiazolyl moiety in the products serves as the formyl precursor, and the OH residue provides the cross-coupling site for further product elaboration, indicating the robust transformability of the products. In the experiment, the researchers used many compounds, for example, 6-Bromo-2-chlorobenzothiazole (cas: 80945-86-4COA of Formula: C7H3BrClNS).
6-Bromo-2-chlorobenzothiazole (cas: 80945-86-4) belongs to thiazole derivatives. Thiazole is a five-membered, unsaturated, planar, π-excessive heteroaromatic containing one sulfur atom and one pyridine-type nitrogen atom at position 3 of the cyclic ring system. The nitrogen in thiazole is sp2 hybridized and the lone pair of electrons localized on the nitrogen is less reactive due to increased aromatic character and decreased basicity. It is protonated and alkylated/acylated at nitrogen forming hydrochloride and quaternary thiazolium salt.COA of Formula: C7H3BrClNS
