In 2022,Zhang, Lin-Bao; Xie, Zuowei published an article in Organic Letters. The title of the article was 《Iridium-Catalyzed Selective B(4)-H Acylmethylation of o-Carboranes with Sulfoxonium Ylides》.Quality Control of Trimethylsulfoxonium iodide The author mentioned the following in the article:
A highly efficient Ir-catalyzed regioselective cage B(4)-H acylmethylation of o-carboranyl acids using sulfoxonium ylides as alkylating regents was developed, giving a large class of B(4)-acylmethylated o-carboranes in good to excellent yields with a broad substrate scope under redox neutral condition. The -COOH moiety serves as the traceless directing group and controls both the regioselectivity and monoselectivity. The experimental process involved the reaction of Trimethylsulfoxonium iodide(cas: 1774-47-6Quality Control of Trimethylsulfoxonium iodide)
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.Quality Control of Trimethylsulfoxonium iodide
