Synthesis of Aryl Nitriles using the Stable Aryl Diazonium Silica Sulfates

An efficient method for preparation of aryl nitriles is reported using Cu(I) to catalyse the reaction of aryl diazonium silica sulfates with sodium cyanide under mild conditions at room temperature in water. This method has the advantages of high yields, simple methodology, short reaction times and easy work-up.
