In the presence of an easily prepared supported ruthenium hydroxide catalyst, Ru(OH)x/Al2O3, various primary azides including benzylic, allylic, and aliphatic ones could be converted into the corresponding nitriles in good yields. The Ru(OH)x/Al2O3 catalyst could be further employed for synthesis of amides in water from benzylic or aliphatic primary azides.
