Larock, Richard C. published the artcileMercury in organic chemistry. 24. Mercuration and subsequent carbonylation of 4-hydroxy-2-alkyn-1-ones: a novel route to furans, Safety of 2-((2-Methylbut-3-yn-2-yl)oxy)tetrahydro-2H-pyran, the publication is Journal of Organic Chemistry (1983), 48(13), 2151-8, database is CAplus.
HgCl2 readily adds to the CC bond of certain 4-hydroxy-2-alkyn-1-ones (e.g., HOCHMeCCAc) to give vinylmercurials [e.g., HOCHMeCCl:C(HgCl)COMe] which appear to be the 1st syn-addition compounds of HgCl2. These vinylmcercurials readily dehydrate to 3-furylmercurials (e.g., I). Pd-promoted carbonylation of these compounds affords 3-furylcarbonyl compounds
