文摘

Magnetite (Fe₃O₄) nanoparticles supported on charcoal, graphene, or SBA-15 were prepared by a simple solid-state grinding technique and subsequent thermal treatment. The Fe₃O₄ nanoparticles supported on activated charcoal exhibited high catalytic activity and furnished good yields of the alkynyl selenide product in the cross-coupling reaction of diphenyl diselenide and alkynes through activation of C−H and Se−Se bonds under ecofriendly conditions, surpassing traditional copper-based catalysts to effect the same organic transformation.
