New arylselanylpyrazole-copper catalysts: Highly efficient catalytic system for C–Se and C–S coupling reactions

We describe herein the use of arylselanylpyrazole–copper complexes as versatile catalysts for C–Se and C–S coupling reactions. The performance of these complexes for C–Se reactions was investigated in chalcogenoacetylene synthesis. The reactions were carried out under mild and aerobic conditions and afforded selanylalkynes bearing a variety of electron-withdrawing and electron-donating groups. The performance of these catalysts for C–S coupling was investigated through the reaction of aryl halides with thiols and products were obtained in moderate to excellent yields. A plausible mechanism for selenoacetylene synthesis is also suggested, and the 77Se NMR results show that these arylselanylpyrazole ligands act as hemilabile ligands. High-resolution mass spectrometry was used to investigate the intermediates and also to corroborate the proposed catalytic cycle.

A General and highly efficient protocol for the synthesis of chalcogenoacetylenes by copper(I)-terpyridine catalyst

A highly efficient copper-catalyzed Csp-X (X = S, Se, Te) bond-forming reaction of terminal alkynes and diorganyl dichalcogenides has been developed. This transformation was realized through the use of copper(I) iodide as a catalyst, 4′-(4-meth

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.
