| | ALPHA-PYRONE Usage And Synthesis |
| Chemical Properties | clear yellow to brown liquid.
Polymerizes easily upon standing, particularly under alkaline conditions.
Very slightly soluble in water, soluble in
alcohol and oils. | | Uses | 2H-Pyran-2-one (a-Pyrone) is a heterocyclic building block. Photochemistry of 2H-pyran-2-one has been investigated by laser flash photolysis with infrared detection. Ketene and a bicyclic lactone were obtained as major photoproducts. | | Definition | ChEBI: 2H-pyran-2-one is the simplest member of the class of 2-pyranones that is 2H-pyran with an oxo substituent at position 2. | | Synthesis Reference(s) | Journal of the American Chemical Society, 90, p. 2318, 1968 DOI: 10.1021/ja01011a020
