A novel methodology for the α-vinylation of amides with arylacetylenes under metal-free conditions has been introduced. This methodology provides a new protocol to synthesize allylamines. In each product, the amount of the cis-isomer was more than that of the trans-isomer.

The addition of radicals to unsaturated precursors is a powerful tool for the synthesis of both carbo‐ and heterocyclic organic building blocks. The recent advent of mild ways to generate N‐centered radicals has reignited interest in exploiting highly regio‐, chemo‐, and stereoselective transformations that employ these reactive intermediates. While the additions of aminyl, iminyl, and amidyl radicals
