Abstract

Abstract A highly effective visible light-promoted “radical-type” coupling of N-heteroarenes with aryldiazonium salts in water has been developed. The reaction proceeds at room temperature with [Ru (bpy) 3] Cl 2⋅ 6 H 2 O as a photosensitizer and a commercial household light bulb as a light source. Pyridine and a variety of substituted pyridines are effective substrates under these reaction conditions, and only monosubstituted products ...
