The regioselective conversion of propargylicalcohols into previously unreported α,α‐diiodo‐β‐hydroxyketones was achieved by treatment with N‐iodosuccinimide in the presence of a gold catalyst. The corresponding α,α‐dichloro‐β‐hydroxyketones were obtained by treatment with trichloroisocyanuric acid in the absence of a catalyst. The latter reaction can be extended to other alkynols. These transformations
