A regio- and stereocontrolled hydrostanyllation of substituted propargyl alcohols and derivatives has been performed.Tri-n-butylstannyl hydride reacts with different substituted propargyl alcohols to give a mixture of Z/E isomers of vinylstannane with the stannyl moiety bonded to the carbon closest to the OH or OR group.A careful study of the reaction conditions allowed the preparation and isolation of pure Z isomer for a wide set of compounds.The reaction products are unstable under the conditions of preparation.An outline of the possible mechanism of the reaction is described.
A REGIOSELECTIVE SYNTHESIS OF 2-TRIBUTYLSTANNYL-1,3-DIENES

Hydrostannylation of 1-trimethylsilyl-4-hydroxy-2-alkyne derivatives followed by acetylation of the OH group and fluoride ion-catalysed 1,4 elimination of the silyl and the acetate groups afforded 2-stannyl-1,3-dienes with high regio- and stereoselectivit
