Cryptand-22 as an efficient ligand for the copper-catalyzed cross-coupling reaction of diorgano dichalcogenides with terminal alkynes leading to the synthesis of alkynyl chalcogenides

A general and efficient method for the cross-coupling reaction of diorgano dichalcogenides with terminal alkynes using copper iodide/cryptand-22 (CuI/C22) has been developed. This protocol gave alkynyl chalcogenides in moderate to excellent yields in the

Magnetite (Fe3O4) nanoparticles: An efficient and recoverable catalyst for the synthesis of alkynyl chalcogenides (selenides and tellurides) from terminal acetylenes and diorganyl dichalcogenides

We present herein a new and efficient methodology for the synthesis of alkynyl chalcogenides from terminal acetylenes and diorganyl dichalcogenides, catalyzed by Fe3O4 nanoparticles. This new approach provided the desired products in good to excellent yields. Moreover, the catalyst was easily recoverable using an external magnet and reused for further experiments without loss of catalytic activity.

An efficient and general procedure for the synthesis of alkynyl chalcogenides (selenides and tellurides) by alumina-supported Cu(II)-catalyzed reaction of alkynyl bromides and diphenyl dichalcogenides

Alumina (Al2O3) supported Cu(II) efficiently catalyzes the reaction of alkynyl bromides and diphenyl diselenides and ditellurides in presence of Zn dust or indium(I) bromide to provide the corresponding alkynyl selenides and tellurides. The reactions of a wide variety of substituted alkynyl bromides have been addressed. The zinc dust or InBr is required for the cleavage of diphenyl selenides/tellurides. The mechanism of the reaction is established. The yields of products are high and the catalyst is recycled.

A simple and effective approach to the synthesis of alkynyl selenides from terminal alkynes

Alkynyl selenides were prepared under very mild conditions by reacting terminal alkynes with respective diorganic diselenides in the presence of potassium t-butoxide. The advantages of this protocol include the use of readily available substrates and reag

THE REACTION OF TERMINAL ALKYNES WITH THE REAGENT PREPARED FROM BENZENESELENENYL BROMIDE AND SILVER NITRITE. NOVEL EFFICIENT SYNTHESIS OF 1-ALKYNYL PHENYL SELENIDES

1-Alkynyl phenyl selenides were synthesized in good yields by the reaction of 1-alkynes with a new reagent prepared from benzeneselenenyl bromide and silver nitrite.

Cu(I)-CATALYZED REACTION OF TERMINAL ALKYNES WITH PHENYL SELENOCYANATE IN THE PRESENCE OF TRIETHYLAMINE. SYNTHESIS OF ALKYNYL SELENIDES

Treatment of terminal alkynes with phenyl selenocyanate in dichloromethane in the presence of CuX(X=CN or Br) and triethylamine at room temperature gave 1-phenylseleno-1-alkynes in high yields.
