Regio- and stereoselective dimerization of terminal alkynes to enynes catalyzed by a palladium/imidazolium system
Yang, Chuluo,Nolan, Steven P.
, p. 591 - 593 (2002)
A Palladium/imidazolium chloride system has been used to mediate the dimerization of terminal alkynes to enynes. The combination of 1 mol % Pd(OAc)2 and 2 mol % IMes·HCl in the presence of Cs2CO3 as base shows high activit

scheme or table, p. 54 - 56 (2012/02/04)
A gold-catalyzed regioselective homodimerization of -aliphatic terminal alkynes is described. Bulky and less Lewis acidic t-BuXPhosAuNTf2 is the preferred catalyst, and the additive, anhydrous NaOAc, substantially facilitates the reaction. Geor
DIMERIZATION AND CODIMERIZATION OF MONOSUBSTITUTED ACETYLENES BY THE ACTION OF PALLADIUM COMPLEXES

The linear dimerization and codimerization of C5-C12 α-acetylenes with palladium catalyst were investigated systematically.It was shown that the catalyst system Pd(acac)2-PPh3-(C2H5)3Al can be used for selective transformation of α-acetylenes into the corresponding alkenylacetylenes with fairly high yields.
