5-exo atom transfer cyclisation onto alkynes mediated by copper(I) complexes
Clark, Andrew J.,Battle, Gary M.,Bridge, Andrew
, p. 1999 - 2001 (2001)
Multidentate amine derived copper(I) halide complexes mediate the atom transfer radical cyclisation of 1-halo-N-propargylacetamides. While cyclisation of trichloro- and dichloroacetamide derivatives leads to α,β-unsaturated γ-lactams containing the gem-dihalide functional group, monohaloacetamides give rise to either cyclised atom transfer or reduction products depending upon the solvent and catalyst used.

A radical-mediated three-component 1,4-sulfonylarylation of 1,3-enynes with aryl iodides and sulfinate salts using cooperative photoredox/nickel catalysis is described. This protocol enables the synthesis of tetrasubstituted sulfonyl-containing allenes under redox-neutral conditions and provides a versatile 1,3-enyne 1,4-difunctionalization platform for the synthesis of a diverse range of tetrasubstituted allenes with high chemo- and regioselectivities, excellent functional group tolerance, and a broad substrate scope.
