Recent progress in the electrochemical selenofunctionalization of alkenes and alkynes

Abstract

The recent advances on the electrochemical selenofunctionalization of unsaturated C–C bonds were comprehensively summarized in this review.

Recent advances in selective mono-/dichalcogenation and exclusive dichalcogenation of C(sp2)–H and C(sp3)–H bonds

“…Addition reactions, especially via double functionalization of unsaturated compounds, have also been broadly applied for the synthesis of chalcogen-bearing compounds. 25,[48][49][50][51][52][53][54][55][56] However, complicated chemo-, regio-and stereoselective issues exist under certain circumstances. Over the past two decades, the direct chalcogenation of C-H bonds has evolved as a straightforward, atom-and step-economical method for the preparation of chalcogenated compounds including organyl sulfides, selenides, sulfones, trifluoromethylthioethers, thiocyanates and selenocyanates.…”

Electrochemical Oxidative Sulfonylation–Azidation of Alkenes

“…Nowadays, electrochemical synthetic strategies have attracted widespread attentions and present the excellent prospect and potential of difunctionalization of alkenes, including the formation of new chemical bonds such as C–O, , C–S, ,, C–C, , C–N, ,, and C–Se ,, bonds. In these strategies electrons could interact with substrates directly at the anode or cathode, thereby avoiding the demand for metal catalysts or exogenous oxidants .…”

Zn(OTf)2-catalyzed intra- and intermolecular selenofunctionalization of alkenes under mild conditions

“…23 To demonstrate the powerful flexibility of zinc catalyst in the construction of a C–Se bond, herein, we wish to report a Zn(OTf) 2 -catalyzed intra- and intermolecular selenofunctionalization of alkenes with electrophilic N -PSP as a continuation of our interest in the selenofunctionalization of different alkenes (Scheme 2b). 9–11,24…”
