AbstractEthylsulfonyl acetonitrilewhich is a key intermediate for the preparation of super-efficient sulfonylurea herbicide rimsulfuronwas prepared via oxidation of ethylthio acetonitrile by hydrogen peroxide. The process afforded the title compound in 90% yield with a purity of above 98% under catalysis of sodium tungstate in acetic acid. |
