A metal-free room temperature decarboxylative cross-coupling between cinnamic acids and arylsulfonyl hydrazides has been realized for the first time for the synthesis of (E)-vinyl sulfones. The scope and versatility of the reaction has been demonstrated by the regio- and stereoselective synthesis of 22 derivatives with diverse structural features.
An operationally simple Eosin Yc atalyzed sulfenylation of hydrazones has been realized to afford ar ange of thioethers under visible light. The methodology provides high yields of thioethers under ambient conditions employ-ing readily availablea nd inexpensive startingm aterials. The reactionh as broad substrate scopea nd is compatible with variousfunctional groups.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.
