Abstract

Starting from 1-adamantanyl-3-imidazole, a number of new 1-adamantanyl-3-benzylimidazolium salts and corresponding unsymmetrically substituted Pd(II) PEPPSI-type complexes were prepared, including dichloride, dibromide, and diiodide. Single crystal X-ray crystallography confirmed solid state structures in six cases. The complexes reported in this work displayed moderate activities as precatalysts for CH activation/arylation reaction of substituted thiophenes.
