The three-sulfur compounds formed on oxidation of the β-keto dithio acids prepared by the reaction of activemethylenecompounds with base and carbondisulfide have been shown to be 3,5-bis(acylmethylene)-1,2,4-trithiolane derivatives. In several cases, two of the three possible geometrical isomers have been isolated and provisional stereochemical assignments have been made. The i.r. and u.v. spectra
