Abstract

A complex of composition [Cu^I₄Cu^II(mtpo)₄(H₂O)₂Cl₂]_n (1) was synthesized from reaction of Hmtpo (Hmtpo = 5-methyl-[l,2,4]-triazolo-[l,5-a]-pyrimidin-7-o1) with one equivalent of CuCl₂·2H₂O in water at 100 °C under autogenous pressure. Complex 1 was fully characterized by X-ray single crystal diffraction, elemental analysis and IR spectroscopy. X-ray analysis reveals that complex 1 is a mixed-valence coordination polymer and displays 1-D chain structure. Compound 1 was able to heterogeneously catalyze the ketalization reaction of 2-butanone and ethylene glycol to afford 2-ethyl-2-methyl-[1,3]-dioxolane in excellent yield under mild conditions.

Catalytic activity of CuI/CuII cyanide based phenanthroline-bicarbonate system for enhancing aerobic oxidation of 2,6-di-tert-butylphenol
2022, Journal of Saudi Chemical Society
The metal organic framework {[Cu₂(CN)₃(phen)₃]5H₂O} MOF1- bicarbonate system was investigated as an efficient catalyst for aerobic oxidation of 2, 6-di-tert-butylphenol (2,6- DTBP). The catalytic system showed very efficient catalytic behavior for the oxidation of selective coupling of 2,6- DTBP to 3,3′,5,5′-tetra-tert-butyl-4,4′-diphenoquinone (DPQ) in excellent yield. The influence of reaction parameters on the selective oxidation of 2, 6-DTBP to DPQ had been investigated. Photoluminescence probing technology of Disodium salt of terephthalic acid as well as scavenging experiments revealed the creation of the hydroxyl radicals as the main active oxidation radicals produced by the MOF1/O₂/basic bicarbonate system. The oxidation reaction mechanism was also discussed. The recycled catalytic system retained its activity for eight successive runs.
Manganese(II) and Copper(I) Compounds Based on Two Derivatives of Imidazo[1,5-a]pyridine: Synthesis, Structures, Magnetic Properties, and Catalytic Activity①
2022, Chinese Journal of Structural Chemistry
The utilization of 2,6-bis(imidazo[1,5-a]pyridin-3-yl)pyridine (bipp) and 3-(pyridin-2-yl)imidazo[1, 5-a]pyridine (pip) in the compounds of manganese(II) and copper(I) ions is presented. Two complexes, [Mn(bipp)(SO₄)(H₂O)]_n (1) and [Cu(pip)₂]ClO₄ (2), were prepared with different characteristics in structure. Compound 1 exhibits a one-dimensional chain topology, and 2 is a homoleptic Cu(I) complex. The dc magnetic susceptibility investigations reveal the antiferromagnetic (AF) Mn^II···Mn^II interactions in complex 1. The catalytic activity of compound 2 toward ketalization reactions was studied. Complex 2 exhibits high activity for the ketalization transformations of aliphatic ketones.
Recent advances in 1,2,4-triazolo[1,5-a]pyrimidine chemistry
2019, Advances in Heterocyclic Chemistry
The review deals with the pharmaceutically and agrochemically important group of 1,2,4-triazolo[1,5-a]pyrimidines (TPs) and covers relevant literature published from about 2006 through 2018. The synthetic section describes the formation of TPs from both aminotriazoles and pyrimidine derivatives by anellation of a second heterocyclic ring. In the structure-related section NMR spectra are stressed. Carbon–carbon coupling reactions and nucleophilic substitutions of functional groups provide the main focus of the reactivity-based section. Finally, progress in application is described.
Mono- and bimetallic nano-Re systems doped Os, Mo, Ru, Ir as nanocatalytic platforms for the acetalization of polyalcohols into cyclic acetals and their applications as fuel additives

Usually, the reactions are conducted in an inert gas atmosphere in a temperature range of 70–110 °C, which yields a conversion rate of 60–95% depending on the method that is used [34–37]. Catalytic methods are based on metals (Fe), transition metal complexes, e.g. Cu, Ir [36,38] or metal oxides (ZrO2) that are supported on silica or aluminosilicates [34,35], surface-modified activated carbon [37] or polymeric fibers [39]. Other solutions include the use of low-temperature catalysts such as an SnO2 doped with W or Mo [30], ionic fluids [40] or the Amberlyst ion-exchange resin [41].
We report here that the Re/SiO₂ catalyst can be a suitable low-cost catalyst for processing polyols into acetals in solvent-free conditions with a high conversion rate and selectivity up to 100% in mild conditions. During a complex investigation, we broadly tested the blending potential of the acetals that were formed by measuring properties such as density, viscosity, isentropic compressibility, isobaric thermal expansion, cetane number and other parameters of both the crude additives and the blends that were prepared with petroleum diesel oil. The results indicate that the investigated acetals can generally be used for blending with petroleum diesel oil in order to obtain the valuable biofuels that are in great demand in the contemporary transportation industry due to the regulatory restrictions that have been introduced in order to protect the environment.
Nano silica and molybdenum supported Re, Rh, Ru or Ir nanoparticles for selective solvent-free glycerol conversion to cyclic acetals with propanone and butanone under mild conditions

Glycerol acetalization is an interesting alternative that can provide biodiesel additives, for example. The vast majority of reactions between polyols and ketones are performed by simply using strong inorganic or organic acids (H2SO4, HCl, HNO3, dichloroacetic acid, p-toluenesulphonic acid) as catalysts [4,5], while other reactions are carried out in organic solvents, such as toluene [6], 1.4-dioxane [7], tetrahydrofuran [8], cyclohexane [9,10], dichloromethane [11]. These reactions can also be catalyzed by the complexes of d-block metals, e.g. Cu, Ir [6,12], metal oxides (ZrO2) supported on silica or aluminosilicates [13,14], active carbon modified on the surface [7] or polymer fibers [9].
We described the preparation of a series of new catalysts, i.e., nano-silica supported Re, Ru, Ir, Rh NPs as well as various combinations of the above-mentioned metals as potential catalysts of glycerol acetalization with acetone or butanone for the first time. In fact, it was discovered that nano-SiO₂ supported Re in particular is a highly efficient selective catalyst of glycerol acetalization for five-membered cyclic acetals. While Re supported on nano-SiO₂ prefers five-membered cycles its replacement to Mo destroys this selectivity and both five- and six-membered products can be observed. Under optimal conditions, the TON that was observed significantly outperforms those that have been reported in the literature for other catalytic systems.
