Cyclocarbonylation of silicon tethered enynes derived from propargylic alcohols and vinylsilanes: A new reductive Pauson-Khand reaction with a traceless tether

Reichwein, John F.,Iacono, Scott T.,Patel, Mittun C.,Pagenkopf, Brian L.

, p. 3739 - 3741 (2002)

In nitrile solvents vinylsilyl ethers of propargylic alcohols undergo Pauson-Khand reaction with polysiloxane extrusion and concomitant reduction of the propargylic C-O bond. The product enones are formally the result of an intermolecular PKR reaction with ethylene.
