Conditions

Temperature: 140 °C

Procedure

A mixture of 2,2'-thiobis(4-t-octylphenol) (44.2 g.) and anhydrous potassium carbonate (6.9 g.) was heated in refluxing 2-propanol for about 0.5 hr. and then cobalt (II) acetate tetrahydrate (12.5 g.) was added. The reaction mixture was stirred at reflux temperature for about 4 hr. during which a precipitate of pink solids was formed. The mixture was filtered and the solids were washed with water and dried. The solids were recystallized from 2-propanol and the resulting pink solid, m.p. 355°-357° C. was dealcoholated by heating at 140° C. at less than 0.1 mm of mercury to give the cobalt 2,2'-thiobis-(4-t-octylphenolate) as a brownish solid m.p. greater than 360° C.
