27.1.3.2.1.2 Variation 2: With Ylides Formed by Reaction with Carbenes

DOI: 10.1055/sos-SD-027-00002

Aggarwal, V.; Richardson, J.Science of Synthesis, (20042776.

The use of dihalocarbenes for the generation of sulfonium ylides for epoxidation has met with little success. Presumably the ylides formed are not sufficiently stable to react before potential rearrangements occur. The situation is further complicated by possible oxidation of sulfides to sulfoxides by dichlorocarbene under aqueous phase-transfer conditions.[‌242‌]
