A class of iron(III) complexes containing diversely substituted cross‐bridged cyclams ( 1‐R,R′: 1‐Me,Me, 1‐Me,Et, 1‐Et,Et, 1‐Me,Bn, 1‐Bn,Bn ) has been prepared and characterized. 1‐R,R′ catalyze the oxidation alcohols to ketones in green conditions, by using tert ‐butylhydroperoxide as oxidant aqueous solutions. They also exhibit catalytic activity water (WO) molecular oxygen driven NaIO 4 , results were found be dependent on steric hindrance R ‐substituents. Best compromise terms...
The growing production of biodiesel as a promising alternative and renewable fuel led the main problem dramatic increase its by-product: glycerol. Different strategies for glycerol derivatization have been reported so far, some more efficient or sustainable than others. Herein, we report very eco-friendly transformation in nontoxic solvents chemicals (i.e., solketal, ketals), proposing three new families Fe(III) compounds capable catalysing acetalization with unpublished turn over...
This work describes the use of simple zinc(II) salts (ZnCl2, ZnCO3, Zn(OAc)2, ZnO, Zn(ClO4)2, Zn(TfO)2, and Zn(BF4)2) as effective catalysts for esterification fatty acids with long-chain alcohols polyols through a homogeneous system that allows gradual selective removal water. The results show catalytic activity depends on nature counterion: most are poorly coordinating anions (perchlorate triflate) or containing basic Brønsted (oxide, acetate, carbonate). However, only latter is it...
Neurodegenerative diseases are often caused by uncontrolled amyloid aggregation. Hence, many drug discovery processes oriented to evaluate new compounds that able modulate self-recognition mechanisms. Herein, two related glycoconjugate pentacoordinate Pt(II) complexes were analyzed in their capacity affect the self-aggregation of amyloidogenic fragments, Aβ21–40 and Aβ25–35, C-terminal region β-amyloid (Aβ) peptide, major component Alzheimer's disease (AD) neuronal plaques. The most...
Abstract This work describes two sustainable methods for production and purification of azelaic acid (AA) to replace the current process ozonolysis oleic (OA). The first proceeds in steps, coupling smooth oxidation OA 9,10‐dihydroxystearic (DSA) with subsequent oxidative cleavage by sodium hypochlorite. An alternative methodology is also proposed, using a chemocatalytic system consisting H 2 O /H WO 4 direct double bond at 373 K. A convenient technique separation proposed.
Octahedral Pt(IV) complexes (2Pt–R) containing a glycoconjugate carbene ligand were prepared and fully characterized. These are structural analogues to the trigonal bipyramidal Pt(II) species (1Pt–R) recently described. Thus, an unprecedented direct comparison between biological properties of Pt compounds with different oxidation states almost indistinguishable features was performed. The stability profile novel in reference solvents determined compared that analogous complexes. uptake...
The growing concern about global warming and the consumption of fossil fuels has driven in recent decades use biomass as a renewable feedstock. In this context, vegetable oils, corresponding fatty acids (FAs) esters (FAEs) have primary importance: their esterification transesterification lead to innovative products, that find application several sectors, from biofuels solvents, surfactants cosmetic ingredients plasticizers. Lewis acid catalysis represents most accredited methodology for...
Herein, the effects of a novel half-sandwich Os(II) complex on aggregation an amyloid model system, derived from C-terminal domain nucleophosmin 1 protein (NPM1264–277), were investigated. The thioflavin T (ThT) binding assay revealed that [(η6-toluene)Os(NHCglu)Cl2] (where NHCglu is N-heterocyclic carbene ligand 1-methyl-3-{2,3,4,6-tetra-O-acetyl-1-glucosyl}imidazol-2-ylidene), hence named Os-Tolu, was able to repress in dose-dependent way.

The complex lacking the sugary portion fails recognition cancer results support use glycosylation design Pt-based anticancer agents.
In this work, γ-valerolactone (GVL), a green solvent based on largely available biomass (carbohydrates), highly biodegradable, and with low eco-toxicological profile, was used as electrolyte component in energy storage devices. This allowed the realization of electrolytes good transport properties high thermal stability, which could be successfully applied electrical double layer capacitors (EDLCs). GVL-based EDLCs operate at 2.7-2.9 V displayed performance term capacitance, cycling well...
This article describes the synthesis and characterization of novel cationic five-coordinate Pt(II) complexes containing nitrogen sugar-based ligands. The cytotoxicity was evaluated on different cell lines with expectation that both coordinative saturation sugar moiety cooperate to enhance their biological activity. In fact, resulted be more active than cisplatin but still little selectivity. They activate apoptosis pathway. Binding representative compounds DNA studied by ethidium bromide...
Abstract This work demonstrates the possibility of using pelargonic acid (PA) esters as solvents for vegetable‐based varnishes. First, PA was efficiently produced through a chemocatalytic cleavage oleic acid, practicing an optimized scale‐up previously developed conditions. then esterified with several alcohols ROH (R = Me, i ‐Pr, n ‐Bu, ‐Hex, 2‐ethylhexyl, and sec ‐octyl) products were formulated commercial rosin (Phenolic Modified Rosin Esters). Dynamic light scattering (DLS) measures...
Five‐coordinate platinum(II) complexes represent a minority compared to the well‐known class of square‐planar species. However, since first appearances in literature, their general properties have attracted much interest. In particular, potential act as anticancer agents has been considered, and several studies demonstrated effectiveness pro‐drugs. The review traces progress these investigations over time subsequent refinements structures. It also reports synthesis, properties, cytotoxic...
Abstract An unprecedented direct oxidation of high‐oleic triglycerides to produce azelaic glycerides has been carried out by using a catalytic system based on H 2 WO 4 /H O . The results are highly competitive with those reported so far for simpler feedstock: at low catalyst loading the proceeds satisfactory yields also starting from real waste oil matrix without any prior purification.
