Sulphonomercuriation route to vinyl and ethynyl sulphones

Ethynyl sulphones were obtained from the reaction of substituted acetylenes with mercury(II) chloride and sodium benzenesulphinate followed by oxidative demercuriation.

Synthesis of (E)-iodo vinylsulfones via oxidative addition of thiol into alkyne under metal free condition

An efficient, transition-metal free and molecular iodine promoted protocol for the construction of (E)-β-iodovinyl sulfone derivatives via oxidative C–S coupling of thiol and alkyne has been demonstrated. Both aryl and alkyl terminal acetylenes were found to be an excellent substrate for the present reaction which provides a wide range of β-iodovinyl sulfone derivatives with very good yield and excellent regio and stereo-selectivities. Diaryldisulfide is also found to be an equally efficient sulfonyl group surrogate under identical reaction conditions.

Decatungstate as Direct Hydrogen Atom Transfer Photocatalyst for SOMOphilic Alkynylation

A versatile approach for the alkynylation of a variety of aliphatic hydrogen donors, including alkanes, is reported. We used tetrabutylammonium decatungstate as photocatalyst to generate organoradicals from C-H/Si-H bonds via hydrogen atom transfer. The l
