| titleOfInvention | Method for preparing lactone compounds |
| abstract | The invention discloses a method for preparing lactone compounds, which takes cyclic ketone compounds as raw materials, takes cyclic organic nitroxide free radicals as catalysts and adds a certain amount of aldehyde auxiliary agents for reaction in an oxygen-containing atmosphere. The invention discloses a preparation method of metal-free catalytic oxidation with mild condition, high safety and high selectivity, which greatly reduces the dosage of aldehyde auxiliary agents, improves the efficiency and range of the aldehyde auxiliary agents and can obtain lactone compounds with high yield. |
