Stereoselective synthesis of α,α-difluoro-β,γ-alkenyl ketones by free-radical reaction of iododifluoromethyl ketones with alkynes

Add time:09/05/2019    Source:sciencedirect.com

A method for stereoselective synthesis of α,α-difluoro-γ-iodo-β,γ-alkenyl ketones via radical difluoroacetylation of iododifluoromethyl ketones with terminal and internal alkynes was reported. This methodology provides a straightforward access to 3,3-disubstitued allylic difluorides.
