DOI: 10.1002/ajoc.202400059

Abstract: Hydroiodic acid‐mediated vicinal iodosulfonylation reaction of alkynes with sodium sulfinates is proposed for the synthesis of (E)‐β‐iodovinyl sulfones. The method is easy to operate, environmentally friendly, using inexpensive and easily available raw materials, and giving… read more here.

DOI: 10.1021/acs.orglett.0c00575

Abstract: A novel and direct disulfonylation reaction of commercially available terminal alkynes under copper(I)/bromodifluoroacetate cocatalyst has been realized. This protocol provides a facile and practical pathway to selectively access (E)-1,2-disulfonylethenes, in which features good functional group… read more here.

Published in 2023 at "Molecules"

DOI: 10.3390/molecules28114436

Abstract: The subject of this investigation is a new method for the construction of sulfonylated heterocycles which overcomes the limitations of classical approaches using a cheap feedstock sulfonylating agent, especially under photocatalyst- and metal-free conditions. read more here.
