A novel synthesis recipe for β-alkoxy methylsulfides was developed via NH4I-mediated three-component oxysulfenylation reaction of styrenes with DMSO and alcohols. This method features simple operation and readily available starting materials, and it provides an alternative sulfenylating agent generated from DMSO for oxysulfenylation reactions.

Diverse substituted pyridines and pyrimidines with high selectivity were obtained using a concise and efficient protocol developed herein. The reaction proceeds via metal-free cascade annulation of isopropene derivatives. Using isopropene derivatives as C3 synthons, NH4I as the “N” source, and formaldehyde or dimethyl sulfoxide as the carbon source, this reaction realizes the efficient formation of

The reaction of dimethylsulfide ditriflate with alkenes leads to the corresponding sulfonium salts. Dependence of the reaction course on the substrate structure is discussed. In the reactions with norbornene and norbornadiene the sulfonium salts with nortricyclene skeleton were obtained. The configurations of the two isomeric disubstituted nortricyclanes 21a,b were determined by NMR.
