Artykuł
Efficient cross-coupling and carbonylative coupling of terminal alkynes with aryl iodides catalyzed by PdCl2(P(O3)2 in the presence of NEt3
in toluene and in ionic liquids is described. In imidazolium ionic liquids, [bmim]PF6
or [mokt]PF6(bmim = 1-butyl-3-methyl imidazolium cation, mokt=1-methyl-3-octyl imidazolium cation) catalyst was recycled and used in four concecutive
catalytic cycles with high activity. In the absence of aryl iodide the same catalytic system catalyzed head-to-tail dimerization of
phenylacetylene to the 1,3-diphenyl enyne,trans-PhCCAC(Ph)CH2;with a yield of 85%
