Novel compounds, 4-tert.-butyl-1,2-benzenedithiol and bis(4-tert.-butyl-1,2-dithiophenolate) metal complexes having the general formula of ##STR1## 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.
提供具有以下一般公式的新化合物,4-叔丁基-1,2-苯二硫醇和双(4-叔丁基-1,2-二硫代苯酚酸鹽)金屬配合物:其中M代表三價過渡金屬,A代表季銨鹽。新的苯二硫醇是通過在溶劑中將4-叔丁基苯硫醇或二(4-叔丁基苯基)二硫化物與單氯化硫反應,然後在碘或路易斯酸存在下將所得產物還原為鋅、錫、鐵和鋁之一的金屬存在下進行反應而製備的。新的銅、鈷和鎳配合物是通過在氧化性氛圍下,在溶劑中將苯二硫醇與相應的二價過渡金屬鹽和一種碱金屬或氫化金屬以及一種季銨鹽反應而製備的。這些配合物在紫外線、可見光或近紅外區域強烈吸收光線,可用作製備光學信息記錄媒體的中間產物。
