title: Coupling of alkynylTMS derivatives with vinylic iodides. An efficient route to 1,3-enynes and dienes.
abstract: [reaction: see text] CuCl-promoted coupling of alkynylTMS derivatives with vinyl iodides leads to 1,3-enynes in high yield. Enynes prepared from homopropargylic alcohols undergo intramolecular hydrosilylation and subsequent silyl cleavage with TBAF to afford 1,3-dienes.
