A novel protocol for the regioselective intermolecular amination of various arenes has been developed. By using an I(III) oxidant in the presence of a Au(I) catalyst, a direct and novel route for regioselectively accessing a variety of substituted aniline moieties has been achieved with yields as high as 90%. Mechanistic insight suggests that regioselectivity can be predicted based on electrophilic aromatic metalation patterns.
Process for the production of cyclic carboxylic acid imides

, (2008/06/13)
In a process for reacting an aromatic or hydroaromatic alicyclic or heterocyclic dicarboxylic acid or its anhydride with an aliphatic or aromatic alicyclic or heterocyclic mono- or di-amine to produce an N-substituted dicarboxylic acid imide with a splitting off of water, the improvement of carrying out the reaction in a liquid solvent mixture consisting essentially of a non-polar organic solvent and a strongly polar organic solvent which together form a ternary azeotrope with water at reaction temperatures between about 40°C. and 160°C. The imide products are generally known for use as intermediates and final products in a number of industries.
