A new Rh(III)-catalyzed [3 + 3] annulation reaction between cyclopropenones and β-ketosulfoxonium ylides has been reported, enabling metal carbene insertion to access a wide range of trisubstituted 2-pyrones I (R = Ph, 2-thienyl, 4-FC6H4, etc.; Ar = Ph, 4-ClC6H4, 4-H3CC6H4) with moderate to excellent yields via C-C single bond cleavage, in which sulfoxonium ylides serve as potential safe precursors of metal carbenes. This reaction occurred under redox-neutral conditions with a broad substrate scope. In the experiment, the researchers used Trimethylsulfoxonium iodide(cas: 1774-47-6Application of 1774-47-6)
Trimethylsulfoxonium iodide(cas: 1774-47-6) reacts with sodium hydride to prepare dimethyloxosulfonium methylide, which is used as a methylene-transfer reagent in synthetic chemistry. It is used to prepare ylide, which reacts with carbonyl compounds to get epoxides.Application of 1774-47-6
