KETONIC DECARBOXYLATION Meaning and
Definition
-
Ketonic decarboxylation is a chemical reaction involving the removal of a carboxyl group (-COOH) from a ketone molecule, resulting in the formation of a new carbon-carbon double bond (C=C). This reaction typically occurs in organic chemistry and involves the breaking of certain chemical bonds within the ketone compound.
In this reaction, a ketone molecule is subjected to specific conditions such as heating or the presence of a catalyst. The carboxyl group attached to the ketone undergoes decarboxylation, meaning it is lost in the form of carbon dioxide (CO2). As a result, the remaining portion of the ketone molecule becomes an alkene, which is a hydrocarbon with a double bond between two carbon atoms.
Ketonic decarboxylation reactions are significant in various areas of organic chemistry, particularly in the synthesis of complex organic compounds. They are often employed as key steps in the creation of certain pharmaceuticals, flavors, and fragrances, as well as in the production of polymers and other industrial materials.
Overall, ketonic decarboxylation is a chemical process that transforms a ketone molecule by removing a carboxyl group, resulting in the formation of a new carbon-carbon double bond. This reaction plays a crucial role in the synthesis of diverse organic compounds used in various fields.
Etymology of KETONIC DECARBOXYLATION
The word "ketonic decarboxylation" is formed by combining two terms: "ketonic" and "decarboxylation".
1. Ketonic: The term "ketonic" comes from the word "ketone", which is a type of organic compound characterized by a carbon-oxygen double bond within a carbonyl group. The word "ketone" is derived from the German word "Keton", which was coined by chemist Leopold Gmelin in the mid-19th century.
2. Decarboxylation: The term "decarboxylation" is composed of two parts: "de-" and "carboxylation". "De-" is a prefix meaning "removal" or "undoing", while "carboxylation" refers to the addition of a carboxyl group (COOH) to a compound.
