Method for producing cyclosulfites |
| abstract |
(57) [Summary] [Object] To provide a method for producing cyclosulfites with a high yield by a method having excellent operability. [Structure] A diol and thionyl halide are added to (a) A process for producing cyclosulfites, which comprises cyclizing in the presence of an inorganic base and (b) a phase transfer catalyst and / or a surfactant. [Effect] Cyclosulfites can be obtained in high yield by a method with excellent operability. |
