Catalytic, metal-free alkylheteroarylation of alkenes via distal heteroaryl ipso-migration.

A new direct alkylheteroarylation of alkenes with simple alkylnitriles via distal heteroaryl ipso-migration has been accomplished under metal-free conditions, in which inexpensive alkylnitriles served as radical precursors, which together with ease of operation makes this process a very practical protocol.
