Copper-catalysed amination of alkyl iodides enabled by halogen-atom transfer

Autor: Anne-Laure Barthelemy, Fabio Juliá, Bartosz Górski, James Douglas, Daniele Leonori

Publikováno v: Nature Catalysis. 4:623-630

Despite the fact that nucleophilic displacement (SN2) of alkyl halides with nitrogen nucleophiles is one of the first reactions introduced in organic chemistry teaching, its practical utilization is largely limited to unhindered (primary) or activate

SYNLETT, 2019, 30 (13), pp.1489-1495. ⟨10.1055/s-0037-1611785⟩

Alkoxyl radicals are highly reactive species which rapidly react by hydrogen atom transfer (HAT) or β-fragmentation to afford a carbon-centered radical. We discuss herein how these RO· radicals can be efficiently trapped in an intermolecular manner
