Azide Radical Initiated Ring Opening of Cyclopropenes Leading to Alkenyl Nitriles and Polycyclic Aromatic Compounds

Abstract We report herein a radical‐mediated amination of cyclopropenes. The transformation proceeds through a cleavage of the three‐membered ring after the addition of an azide radical on the strained double bond and leads to tetrasubstituted alkenyl nitrile derivatives upon loss of N 2 . With 1,2‐diaryl substituted cyclopropenes, this methodology could be extended to a one‐pot synthesis of highly functionalized polycyclic aromatic compounds (PACs). This transformation allows the synthesis of nitrile‐substituted alkenes and aromatic compounds from rapidly accessed cyclopropenes using only commercially available reagents.
