A direct cyanation of terminal alkynes for the synthesis of propionitrile derivatives, with the aid of silver salt using water additive, has been achieved. The cyano source used is N-isocyanoiminotriphenylphosphorane, which is nontoxic, safe, and easy to handle. This protocol is characterized by its operational simplicity, high efficiency with excellent yields, broad substrate scope, and greater functional group tolerance.

A concise copper(I)‐catalyzed oxidativetransformation of aryl propargyl azides to arylpropiolonitriles has been developed. Arylpropiolonitrile derivatives can be obtained in moderate to good yields by this strategy. An oxidative Schmidt rearrangement is involved in this transformation.
