A variety of 1,5-diaryl-1H-imidazoles have been regioselectively synthesized by direct coupling of 1-aryl-1H-imidazoles with aryl iodides or bromides in DMF in the presence of CsF as the base and a catalyst precursor consisting of a mixture of Pd(OAc)2 and AsPh3. The data obtained in this synthetic study support a reaction mechanism involving an electrophilic attack of an arylpalladium(II) halide species

Copper-catalyzed N-arylation of imidazoles can be accomplished using (CuOTf)2·benzene as a copper source and Cs2CO3 as a base in xylenes at 110–125 °C. Addition of 1,10-phenanthroline (phen) and trans,trans-dibenzylideneacetone (dba) was crucial to the success of the process. The products, N-arylimidazoles, were isolated in high yields.

new class of cytochrome P-450 model compounds called the “picnic basket porphyrins.” The picnic basket porphyrins are unsymmetrical porphyrins with one face sterically protected by a superstructure and the other unhindered. The manganese(III) porphyrins have been investigated as shape selective catalysts using oxygen atom donors in the presence of a sterically bulky imidazole. This paper presents ligand
