One type of this reaction is a two-step process involving the formation and disassembly of a carbanion.
One type of this reaction is a two-step process involving the formation and disassembly of a carbanion. One reaction of this kind uses iodomethane and carbon disulfide to produce a xanthate intermediate. After an oxidation by mCPBA treatment, another reaction of this kind involves the disruption of a cyclic amine oxide transition state by simple heating. Those reactions are the syn variety, in which the abstracted hydrogen and leaving group are on the same side. These reactions often compete with substitution reactions, which, like these reactions, have uni- or bi- molecular reaction mechanisms, with the more stable product forming in accordance with Zaitsev's rule. For 10 points, name these reactions, including the Chugaev and Cope varieties, that result in the formation of double bonds.
