Abstract
A new one-step method for the preparation of 2-aryl-1H-imidazoles 3, based on the DMSO dehydrogenation of 2-aryl-Delta2-imidazolines, is described. A comparative study between DMSO and 10% Pd/C, the best known catalyst employ ed in this transformation, has also been developed. Both protocols were car ried out at 120 degreesC for 48 hours.
