Silyl ethers that are synthesized by coupling a propargylic alcohol with an allylsilyl chloride are shown to undergo sulfide-promoted Pauson -Khand reactions, affording bicyclic enones.

Organo-silicon compounds S 0060 Allylsilyl Propargyl Ethers as Substrates for Intramolecular Pauson-Khand Reactions. -Tethering enynes through an allylic silyl ether linkage affords viable substrates for Pauson-Khand reactions. Scope and limitations of the methodology are studied. -(ISHAQ, S.; PORTER*, M. J.; Synth. Commun. 36 (2006) 4-6, 547-557; Dep. Chem., Univ. Coll., London WC1H 0AJ, UK; Eng.) -H. Toeppel 34-175
