Ring Expansion Reaction of Sulfonium Ylides derived from2-Substituted-1,3-Dithiolanes

摘要

In synthetic chemistry,carbenoids generated by metal-catalyzed decomposition ofdiazo compounds are useful species since carbenoids can react with various heteroatoms togive onium ylides,which undergo rearrangement to form a new carbon-carbon bond andcarbon-heteroatom bond.
