4. Alkene Metathesis

Alkene metathesis or olefin metathesis is a C=C forming reaction in which the components of two alkenes are redistributed to form a new C=C bond. This fascinating reaction led to the award of Nobel Prize to Chauvin, Grubbs, and Schrock collectively in 2005. They have worked enormously on the reaction mechanism and kinetics of alkene metathesis.

1.     Wittig Reaction

This Nobel Prize winning reaction was discovered by George Wittig. It involves the reaction of an aldehyde or ketone with phosphorus ylides, leading to the formation of a double bond between carbon atoms.
