Herein, a protocol for rhodium(III)-catalyzed aldehydic C(sp2)-H acylmethylation reactions of quinoline-8-carboxaldehydes I (R = H, 6-(4-methoxyphenyl), 5-(naphthalen-1-yl), etc.) using sulfoxonium ylides R1C(O)CH=S(O)Me2 (R1 = Ph, propan-2-yl, adamantan-1-yl, etc.) as carbene precursors to afford 1,3-diketones II, which readily tautomerized to their enol forms was reported. The reaction mechanism was determined by synthesizing the key intermediate, a five-membered-ring acylrhodium species were determinedTrimethylsulfoxonium iodide(cas: 1774-47-6SDS of cas: 1774-47-6) was used in this study.
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. Further, it reacts with alfa,beta-unsaturated esters to get cyclopropyl esters.SDS of cas: 1774-47-6
