A process for the preparation of lactone compounds |
| abstract |
The invention discloses a method for the production of lactone compounds, wherein a cyclic ketone compound is used as raw material, annular organic nitroxyl radicals are used as a catalyst under an oxygen-containing atmosphere and a certain amount of aldehyde is added as an auxiliary to the reaction. The invention discloses a production method under mild conditions and with high safety and high selectivity to oxidize the substrate with metal-free catalysts, greatly reducing the consumption of the aldehyde additive and improving the efficiency of the aldehyde excipient and the high yield lactone compounds can be produced. |
