The carbonyl band of five-membered lactones (y-lactones) is in the range of 1735-1750 cm, while six-membered lactones (6-lactones) absorb in the range of 1760-1780 cm. Five-membered …

Lactones are a special kind of ester in the form of a ring. It is often possible to form them via an internal esterification process.

A “lactone” is a cyclic ester and has the general structure. By recognizing that the steps in the acidic hydrolysis of an ester are exactly the same as those in a Fischer esterification (but in …

Cu/nitroxyl catalysts promote a highly efficient and selective aerobic oxidative lactonization of diols under mild reaction conditions using ambient air as the oxidant.

Lactones are cyclic organic esters of hydroxycarboxylic acid, usually formed when hydrogen or halogen atoms react with any carboxylic group present in the same molecule. All this process …
