METHOD FOR PRODUCING NEW SWEAT LYLIDS |
| abstract |
The aim and the object are to produce in a simple manner new sulfur ylides of pyrazolin-5-ones with good yields and in high purity. According to the invention, 2-pyrazolin-5-ones are reacted with a sulfoxide at from 10 to 150 ° C., optionally in the presence of solvents with thionyl halides or acid anhydrides, to give the corresponding sulfonium salts and then neutralized with bases to give the sulfur ylides of the pyrazolin-5-ones. |
