“…More interestingly, the mass properties of the material are maintained throughout this approach for surface modification. In the other step, the p‐arsanilic acid stabilized on the rGO was converted into arsine oxide using thionyl chloride, and subsequently with sodium hydroxide . Trivalent arsine oxide has a greater affinity than pentavalent arsenic acid in the chemical reactions, but as trivalent arsine oxide is more toxic than arsenic acid, the separation of the reaction product was not performed in this step.…”

In the present work, ruthenium nanoparticles were synthesized on functionalized reduced graphene oxide (rGO). First, the surface of rGO was modified with two para‐arsanilic acid and dithiooxamide promoters to create the rGO with scattered hydrophilic positions. The ruthenium nanoparticles were synthesized and immobilized simultaneously in small hydrophilic micro‐reactors under mild conditions. Characterization of the synthesized nanocatalyst was confirmed with different techniques, such as transmission electron microscopy (TEM), X‐ray diffraction, Fourier transform‐infrared and scanning electron microscopy. TEM images of the synthesized catalyst show the Ru nanoparticles have diameters less than 6 nm. The designed nanocatalyst was investigated for the selective liquid phase oxidation of cyclohexene with molecular oxygen in an autoclave under solvent‐free conditions, which obtained a maximum of 91% conversion and 90% selectivity under optimized conditions. The catalytic activity over rGO‐AO‐TO/Ru recycled catalyst remained at a satisfactory state after at least five runs.

This article describes the preparation of the unnatural arsonolipids 7-9, pseudo arsonolipids 10 and 11, and arsinolipids 12-14 (Fig. 3). Their preparation was motivated by the unique properties of the arsenic compared to phosphorus atom of the -AsO 3 H 2 and >AsO 2 H groups. It was anticipated that these lipids will show interesting physical, chemical, biochemical and biological properties. Two key points in their preparation have been identified and studied: the preparation of the precursor hydroxy-containing arsonic and arsinic acids and their subsequent acylation to the corresponding arsono-and arsinolipids. The most intensively studied were the arsonolipids 7 which showed quite interesting physical properties forming in water super structures and interacted with carbonic anhydrase and phospholipase A 2 . They formed arsonoliposomes either in the absence or in the presence of cholesterol and a phospholipid. The latter arsonoliposomes alone, i.e. in the absence of a trapped drug, revealed quite promising selective toxicity against protozoal parasites, various cancer cells in vitro and prostate cancer in vivo.
