The coupling of aryl or vinyl halides with terminal acetylenes catalysed by palladium and
other transition metals, commonly termed as Sonogashira cross-coupling reaction, is one of …

Symmetrical diarylalkynes were obtained from propiolic acid (or 2-butynedioic acid) and aryl
halides in good yields. The optimized reaction conditions were 2.0 equiv of aryl halide, 1.0 …

It is of great significance to realize the alkynylation of the reaction since alkynes are widely
present in natural products and biologically active molecules. And at the same time alkynes …

L2Pd (0) and L2Pd (II) complexes, where L= t-Bu2 (p-NMe2C6H4) P, have been identified
as efficient catalyst systems for the Heck alkynylation of a variety of aryl bromides (17 …

An efficient and general protocol for the deacetonative Sonogashira coupling of aryl
propargyl alcohols with aryl chlorides is described. The reaction proceeded smoothly with …

Unsymmetrical diarylalkynes are accessible by a one-pot procedure from two different aryl
halides and (trimethylsilyl) acetylene. The three-component coupling is initialized by a …

Efficient copper-free Sonogashira coupling of aryl chlorides with palladium on charcoal -
Chemical Communications (RSC Publishing) DOI:10.1039/B810928A Royal Society of …

Extensive study of different amine–water solvent mixtures was carried out for copper free
Sonogashira coupling of aryl iodides. The influence of the palladium sources, ligands …

A convenient Pd-and phosphine-free protocol for assembling internal alkynes from tertiary
propargyl alcohols and (het) aryl halides has been developed. The proposed tandem …

The low loading combination of the complex [9, 9‐dimethyl‐4, 5‐bis (diphenylphosphino)
xanthene](Xantphos) copper (I) iodide and simple ligand‐free palladium (II) acetate was …
