A new type of ligand-free Ni-nanoparticles supported onrGO (size distribution average d = 9 ± 3 nm) was prepared and fullycharacterized via morphological (Fe-SEM), structural (P-XRD, HR-TEM),and spectroscopic (ICP-EOS, XPS) analysis tools. The metal compositewas effectively employed in the unprecedented heterogeneously Ni-as-sisted cross-coupling reaction of aryl/vinyl iodides and thiocarboxylates.A range of sulfur-containing aryl as well as vinyl derivatives (15 exam-ples) was achieved in high yields (up to 82%), under mild reaction condi-tions, and with wide functional group tolerance.

Abstract
A new type of ligand-free Ni-nanoparticles supported onrGO (size distribution average d = 9 ± 3 nm) was prepared and fullycharacterized via morphological (Fe-SEM), structural (P-XRD, HR-TEM),and spectroscopic (ICP-EOS, XPS) analysis tools. The metal compositewas effectively employed in the unprecedented heterogeneously Ni-as-sisted cross-coupling reaction of aryl/vinyl iodides and thiocarboxylates.A range of sulfur-containing aryl as well as vinyl derivatives (15 exam-ples) was achieved in high yields (up to 82%), under mild reaction condi-tions, and with wide functional group tolerance.File in questo prodotto:
