ABSTRACT Novel compounds, 4-tert.-butyl-1,2-benzenedithiol and bis(4-tert.-butyl-1,2-dithiophenolate)metal complexes having the general formula of Image wherein M represents a trivalent transition metal, and A represents a quarternary ammonium are provided. The novel benzenedithiol is produced by reacting 4- tert.-butylbenzenethiol or di(4-tert.-butylphenyl)disulfide with sulfur monochloride in the presence of iodine or a Lewis acid in a solvent, and then reducing the resultant product with a metal selected from the group consisting of zinc, tin, iron and aluminum in the presence of an acid. The novel Cu, Co and Ni complexes are produced by reacting the benzenedithiol with a salt of the corresponding divalent transition metal in the presence of an alkoxide metal or a hydride metal and a quarternary ammonium salt in a solvent under an oxidative atmosphere. The complexes strongly absorb rays in the region of ultraviolet, visible or near infrared, and are useful intermediates for the production of optical information recording media.
