Abstract A method for the synthesis of amide‐containing molecules was developed using vinyl azides as an enamine‐type nucleophile towards carbon electrophiles, such as imines, aldehydes, and carbocations that were generated from alcohols in the presence of BF 3 ⋅OEt 2 . After nucleophilic attack of the vinyl azide, a substituent of the resulting iminodiazonium ion intermediate migrates to form a nitrilium ion, which is hydrolyzed to afford the corresponding amide.
