NiNP@rGO Nanocomposites as Heterogeneous Catalysts for Thiocarboxylation Cross-Coupling Reactions

abstract:
A new type of ligand-free Ni-nanoparticles supported on
rGO (size distribution average d = 9 ± 3 nm) was prepared and fully
characterized via morphological (Fe-SEM), structural (P-XRD, HR-TEM),
and spectroscopic (ICP-EOS, XPS) analysis tools. The metal composite
was 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.
