Photochemical and Thermal Transformations of Unsymmetrical Di-O-alkyl-S,S-phthaloyl Dixanthates

Phthaloyl chloride (I) reacts with potassium O-alkylxanthates at 0 deg C in ether to give the corresponding unsymmetrical di-O-alkyl-S,S-phthaloyl dixanthates (V).Irradiation of these dixanthates (V) in benzene with a mercury lamp for 7 hr results in the formation of trans-biphthalyl (X).However, thermal decomposition of the dixanthates Va (R = isopropyl) and Vc (R = isoamyl) around 250 deg C for 30 min yields a mixture of X, thiophthalic anhydride (XII), carbonyl sulphide (XIV) and the corresponding O,S-dialkyl xanthates (XIII).
