Reactions of Di-o-tolyl Telluride and Selenide with Palladium Acetate: Isolation of a Novel Palladium Complex of a Tellurenic Acid Anhydride and Related Trinuclear and Tetranuclear Palladium Complexes

The reaction of di- o -tolyl telluride with palladium acetate provided a novel palladium complex of a tellurenic acid anhydride, ( o -tolylTe) 2 OPdOAc 2, and a linear trinuclear complex, [Pd( o -tolyl){di- o -tolyl telluride}] 2 Pd(μ-OAc) 2 . The reaction of di- o -tolyl selenide with palladium acetate afforded a tetranuclear complex of rare geometry, [Pd(OAc)(μ-Se- o -tolyl)] 4 .
