Abstract

Xanthates were easily prepared by adsorption of alcohol on KF-Al₂O₃ followed by treatment of carbon disulfide and iodomethane at room temperature. Pyrolysis of benzyl xanthate affords to a complex mixture of products. A radical process was proposed to explain the nature of products obtained.
