Cobalt(III)-catalysed C-H allylation with vinylaziridines

A cobalt-catalysed C-H allylation of aromatic and heteroaromatic compounds with vinylaziridines is described. This transformation occurring under mild reaction conditions proceeds through C-H activation, carbon-carbon double bond insertion and beta-nitrogen elimination. Its scope and limitations have been investigated and a synthetic application of products has been achieved.
