On February 28, 1993, Nadir, Upender K.; Arora, Anjali published an article.Safety of trimethyloxosulphonium chloride The title of the article was A facile synthesis of N-arylsulfonylazetidines through the reaction of N-arylsulfonylaziridines with dimethyloxosulfonium methylide and a PTC [phase-transfer catalyst]. And the article contained the following:
N-Arylsulfonylazetidines (I; R1 = e.g., H, C6H4Me-p; R2 = alkyl, aryl) can be prepared in 18-55% yield by the reaction of corresponding aziridines (II) with dimethyloxosulfonium methylide in the presence of a PTC (e.g., tetrabutylammonium hydrogen sulfate). Aziridines substituted at positions 2 and 3 failed to react. The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Safety of trimethyloxosulphonium chloride
The Article related to ring expansion arylsulfonylaziridine sulfur ylide, aziridine arylsulfonyl ring expansion sulfur ylide, phase transfer ring expansion catalyst arylsulfonylaziridine, azetidine arylsulfonyl and other aspects.Safety of trimethyloxosulphonium chloride
