This review probes the recent developments in stereoselective reactions within area of sulfoxonium ylide chemistry since early 2000s. An abundance research has been applied to its emergence 1960s. There a continued effort then with work traditional areas, such as epoxidation, aziridination and cyclopropanation. Efforts have also novel olefination insertion reactions, develop methodologies using organocatalysis transition metal catalysis. The growing interrupted Johnson–Corey–Chaykovsky is described, whereby unexpected cyclopropanation epoxidation developed. In general, most observed mechanistic pathway ylides formal cycloaddition: (2 + 1) (e.g., epoxides, cyclopropanes, aziridines), (3 oxetanes, azetidines), (4 indanones, indolines). involves formation zwitterionic intermediate through nucleophilic addition carbanion an electrophilic site. intramolecular cyclization occurs, constructing cyclic product. Insertion X–H bonds X = S, N or P) are observed, protonation followed by X, form inserted

A practical strategy for the construction of diverse phosphonyl and thiofunctionalized sulfoxonium ylides via controllable monofunctionalization hybrid I(III)/S(VI) is presented. This process allows efficient P–H insertion under Cu catalysis, enabling synthesis ylides, whereas reaction with sulfur-containing reagents including AgSCF3, KSC(S)OR, KSCN mild conditions resulted in α-trifluoromethylthiolation, dithiocarbanation, thiocyanation accordingly. Of note, wide substrate compatibility (108 examples), excellent efficiency (up to 99% yield), gram-scale experiments, various product derivatizations highlight synthetic utility this protocol.
