Hot couple: Propargyl azides were coupled with carboxylic acids by an iron‐catalyzed dehydrogenativeCObondformation (see scheme). This method enables propargylicCHfunctionalization under mild reaction conditions and also may involve the application of the azido moiety as an assisting group in CH activation.

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.
