In 2019,Advanced Synthesis & Catalysis included an article by Dey, Raghunath; Banerjee, Prabal. Product Details of 1774-47-6. The article was titled 《Metal-Free Ring Opening Cyclization of Cyclopropane Carbaldehydes and N-Benzyl Anilines: An Eco-Friendly Access to Functionalized Benzo[b]azepine Derivatives》. The information in the text is summarized as follows:
In the presence of 0.2 equivalent or 1.2 equivalent of p-TsOH, arylcyclopropanecarboxaldehydes such as I and a bicycloheptanecarboxaldehyde underwent ring opening or tandem ring opening and cyclocondensation reactions with N-benzylic anilines such as II at ambient temperature in CH2Cl2 to yield either γ-aryl-γ-(arylamino)butanals such as III and arylbenzazepines such as IV, resp. IV was reduced to the corresponding tetrahydrobenzazepine. In the experimental materials used by the author, we found Trimethylsulfoxonium iodide(cas: 1774-47-6Product Details 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. Further, it reacts with alfa,beta-unsaturated esters to get cyclopropyl esters.Product Details of 1774-47-6
