A set of 8-arylxanthines was prepared under metal-free conditions and in aqueous solvents from arylazo sulfones and caffeine or theophylline. Notably, the process took place by simply exposing the reaction vessel to visible or solar light, and unreacted xanthine could be easily recovered during the purification step.

This paper describes the synthesis and characterization of silver, copper and gold complexes supported by several amino-NHC ligands with different amino side arms. The transmetallation process using silver-NHC complexes can be used to prepare amino-NHC copper and gold complexes easily in high yield. In addition, the catalytic activities of copper complexes are examined for arylation of caffeine via C-H bond activation.
