Abstract
During a research of the Friedel-Crafts'reaction using xanthate, it was found thatxanthates rearrange to dithiolcarbonates by the catalysis of aluminum chloride in carbondisulfide. This rearrangement needs at least a molar equivalent of aluminum chlorideto xanthates and proceeds even at room temperature. With respect to solvent, carbon disulfide can be replaced by chloroform without essential effect on the product distribution. It was presumed from a study of crossover reaction that this rearrangement might have the nature of intermolecular reaction.
