the synthesis of sulfur ylides via rhodium-catalyzed coupling of in situ generated iodonium ylides with sulfides or sulfoxides has been developed. A wide range of sulfur ylides were obtained in moderate to good yields from inexpensive sulfur compounds and active methylene compounds with a short reaction time (MW, 5–10 min) or 12–16 h at rt. Furthermore, these sulfoxonium ylides were used as novel acceptor/acceptor

A variety of 1,4-dicarbonyl compounds containing vicinal quaternary carbons are efficiently generated in high yields with high diastereoselectivities via Cu(i)-catalyzed homo-coupling of indanone derivatives using diaziridinone as an oxidant.
