OLEFINATION Meaning and
Definition
-
Olefination is a chemical process that involves the formation of carbon-carbon double bonds within organic compounds. It is a reaction used in organic synthesis to create new carbon-carbon double bonds, also known as olefins or alkenes. These double bonds contain a pi bond, which is formed by the overlapping of two parallel p orbitals.
The olefination process can be achieved through various methods, each with its own set of reagents and conditions. One common method is the use of reagents such as strong bases or reagents capable of generating carbanions. This enables the removal of a leaving group from a carbon atom, followed by the attack of a nucleophilic carbon or organometallic group to form the carbon-carbon double bond.
Another widely used method is known as the Wittig reaction, which involves the reaction between an aldehyde or ketone and a phosphonium ylide. The phosphorus atom in the ylide acts as an electrophile, while the carbanionic carbon atom of the ylide acts as a nucleophile. This results in the formation of a new carbon-carbon double bond between the carbonyl carbon of the aldehyde or ketone and the ylide carbon.
Olefination reactions find significant applications in the synthesis of a wide range of organic compounds, including pharmaceuticals, natural products, and polymers. The ability to selectively form carbon-carbon double bonds provides chemists with a powerful tool to construct complex molecules with desired properties.

Etymology of OLEFINATION
The word "olefination" is derived from the term "olefin", which refers to a class of unsaturated hydrocarbons. The term "olefin" originated from the Latin word "oleum", meaning oil, and the Greek word "phainein", meaning to show or appear.
