A facile hydroiodination of alkynes using readily-available reagents such as I2, PPh3, and H2O has been developed. This is extended to the one-pot synthesis of trisubstituted alkenes from alkynes via iodoalkenes using Pd-c

The title reaction was found to proceed in the presence of a rhodium/1,2-bis(diphenylphosphino)benzene catalyst. Variously substituted arylethenes and 1,3-dienes were obtained in good yields. Georg Thieme Verlag Stuttgart.

Aryl- and alkenylsilanediols, which possess two hydroxy groups on the silicon atom, undergo the rhodium-catalyzed addition of an organic group on silicon to internal alkynes. Treatment of several internal alkynes with aryl- or alkenylsilanediols in the pr

Highly selective alkyne-alkyne cross coupling reactions were achieved using Cp2ZrBu2 and ethylene gas.First, alkynes were treated with 1.2 equiv of Cp2ZrBu2 (Negishi reagent) under ethylene gas to give zirconacyclopentenes with high selectivities.Subsequent addition of a second alkyne to the solution of zirconacyclopentenes at 50 deg C gave unsymmetrical zirconacyclopentadienes selectively.After hydrolysis unsymmetrical dienes were obtained in high yields.
PALLADIUM-CATALYSED STEREOSELECTIVE HYDROVINYLATION OF DISUBSTITUTED ACETYLENES: PREPARATION OF FUNCTIONALIZED 1,2,4-TRISUBSTITUTED-1,3-DIENES

Vinyl halides react with disubstituted acetylenes in the presence of the palladium-formate reducing system to give stereoselective formation of functionalized 1,2,4-trisubstituted-1,3-dienes in good to high yield.With arylethynyl,dialkylcarbinols this rea
