Reaction of Sulfur Chlorides with Metal β-Diketonates

Abstract

Metal β-diketonates react with sulfur dichloride to form sulfenyl chlorides irrespective of β-substituent. Bulky phenyl and tert-butyl groups do not prevent formation of fully substituted complexes. The possibility of preparing sulfenyl chloride derivatives of rhodium, ruthenium, and vanadium β-diketonates was demonstrated. A new procedure was suggested for preparing chlorosulfenyl-substituted β-diketonates. Disulfur dichloride reacts with metal chelates with the substitution of both chlorine atoms and formation of polynuclear complexes in which the diketonate groups are linked by disulfide bridges.
