The Pd-catalyzed trans-selective monoalkynylation of 1,1-dihalo-1-alkenes with XZnCCSiMe3, where X is Br or Cl, can proceed generally in excellent yields in the presence of Pd(DPEphos)Cl2 or Pd(dppf)Cl 2, and subsequent al

The cross-coupling of a number of internal arylalkynes with a representative terminal alkyne, tert-butyldimethylsilylacetylene, proceeds regio- and stereoselectively in the presence of a rhodium catalyst to produce the corresponding enyne compounds with g
Gem-selective cross-dimerization and cross-trimerization of alkynes with silylacetylenes promoted by a rhodium-pyridine-n-heterocyclic carbene catalyst

The gem-selective cross-dimerization and -trimerization of silylacetylenes with alkynes through C-H activation using a rhodium(I)-pyridine-N-heterocyclic carbene catalyst have been developed. This reaction is applied to various aliphatic or aromatic termi
Highly selective synthesis of (E)-3-methyl-1-trialkylsilyl-3-en-1-ynes via trans-selective alkynylation catalyzed by Cl2Pd(DPEphos) and stereospecific methylation with methylzincs catalyzed by Pd(tBu3P)2.
