Alkynyl selenides were synthesized by a straightforward one-pot and three-step methodology, without the need of diselenides as starting reagents, under an oxygen atmosphere and using PEG 200 as the solvent. This procedure ...

The selective semi-hydrogenation of terminal alkynes was efficiently performed, under mild reaction conditions (H 2 balloon, 110 °C), promoted by a bimetallic nanocatalyst composed of copper and palladium nanoparticles ...

Readily prepared copper nanoparticles were found to catalyse the 1,3-dipolar cycloaddition of azides and alkynes up to rates comparable to those of microwave chemistry. Both the preparation of the nanoparticles and the ...

Readily prepared copper nanoparticles have been found to effectively catalyse the 1,3-dipolar cycloaddition of a variety of azides and alkynes furnishing the corresponding 1,2,3-triazoles in excellent yields. Both the ...

A simple and mild methodology for the direct synthesis of alkynylphosphonates is presented. The reaction of a variety of terminal alkynes with dialkyl phosphites in the presence Cu2O (14 mol %) led to the formation of the ...

A wide range of catalysts based on supported copper nanoparticles have been prepared and tested in the cross-dehydrogenative coupling of tertiary amines and terminal alkynes. Copper nanoparticles on zeolite Y were found ...

In this paper, we present the synthesis and characterization of new orthopalladated complexes derived from alpha-diphenylhydrazonoketene dithioacetals. From their reaction with terminal alkynes, the intermediates of the ...
