Abstract
![]()
Green catalysts with excellent performance in Cu-free
Sonogashira
coupling reactions can be prepared by the supramolecular decoration
of graphene surfaces with Pd(II) complexes. Here we report the synthesis,
characterization, and catalytic properties of new catalysts obtained
by the surface decoration of multiwalled carbon nanotubes (MWCNTs),
graphene (G), and graphene nanoplatelets (GNPTs) with Pd(II) complexes
of tetraaza-macrocyclic ligands bearing one or two anchor functionalities.
The decoration of these carbon surfaces takes place under environmentally
friendly conditions (water, room temperature, aerobic) in two steps:
(i) π–π stacking attachment of the ligand via electron-poor
anchor group 6-amino-3,4-dihydro-3-methyl-5-nitroso-4-oxo-pyrimidine
and (ii) Pd(II) coordination from PdCl42–. Ligands are more efficiently adsorbed on the flat surfaces of G
and GNPTs than on the curved surfaces of MWCNTs. All catalysts work
very efficiently under mild conditions (50 °C, aerobic, 7 h),
giving a similar high yield (90% or greater) in the coupling of iodobenzene
with phenylacetylene to form diphenylacetylene in one catalytic cycle,
but catalysts based on G and GNPTs (especially on GNPTs) provide greater
catalytic efficiency in reuse (four cycles). The study also revealed
that the active centers of the ligand-Pd type decorating the support
surfaces are much more efficient than the Pd(0) and PdCl42– centers sharing the same surfaces. All of the
results allow a better understanding of the structural factors to
be controlled in order to obtain an optimal efficiency from similar
catalysts based on graphene supports. Green catalysts
with high efficiency in the Cu-free Sonogashira
C−C coupling reactions can be prepared by the supramolecular
functionalization of carbon materials.

Abstract
The paper deals with the recovery of gold (III) from hydrochloric acid solutions on carbon based nanotube material at elevated temperatures under autoclave conditions. It is established that the quantitative recovery of gold (III) from hydrochloric acid solution upon its contact with carbon material occurs at a temperature of 170 °C for 240 minutes. The morphological features of metallic gold particles are studies by scanning electron microscopy

Abstract
The tetracyanoplatinate ligand was employed in synthesizing the first neptunyl cyanoplatinate complexes. Results indicate in situ oxidation of Pt(II) by Np(V/VI) to form mixed-valent Pt-Pt stacked columnar chains linked by cation-cation interaction induced chains of Np(V) polyhedra into a two-dimensional sheet structure. The Pt-Pt stacking distances of 3.04-3.05 Å are the longest reported columnar platinophilic interactions among mixed-valent tetracyanoplatinate structures. These complexes further illustrate the marked chemical differences and structural diversity of solid-state Np(V) coordination complexes with regard to Np(VI) and U(VI).
