Silver nitrate-catalyzed reaction of methyl α,α-disubstituted α-isocyanoacetates with primary amines afforded 3,5,5-trisubstituted imidazolones in good to excellent yields. A silver salt-catalyzed insertion of the isocyano group into the N−H bond of the am ...
Multimetallic cooperative binding of heteroallenes provides an attractive route to their activation, but the reduction of CS2 at heterobimetallic sites, associating an electron-rich metal with a main group Lewis acid has not been explored. Here we show tha ...
Development of selective oxidation catalysts is a major concern of modern chemical industry. Among several systems, VTi-oxide based catalysts showed the most promising and versatile, able to catalyse key reactions like oxidation of o-xylene to phtalic anhy ...
Dry liquid crystal marbles are structures that consist of cholesteric liquid crystal (CLC) droplets prepared by the mixture of chiral-doped thermotropic LCs encapsulated by cellulose nanocrystals (CNCs) that have been dried under ambient conditions. The ch ...
Hydrogenation of aromatic compounds is a widely used catalytic process in modern industry. Selective hydrogenation of benzene (BZ)-toluene (TL) mixtures is an important industrial process as it allows the purification of BZ for further synthetic purposes. ...
In the presence of a catalytic amount of chiral BINOL-derived phosphoric acid (TRIP), reaction of an α-isocyanoacetate 1, an aldehyde 2, an aniline 3 followed by addition of a toluene solution of α,β-unsaturated acyl chloride 5 afforded oxa-bridged tricycl ...
The reaction mechanism on the formation of the hydrosulfido complex [Re(SH)(CO)(3)(bipy)] via the reaction of [Re(OH)(CO)(3)(bipy)] with carbon disulfide was theoretically investigated at the B3LYP/6-31+G(d, p) (LANL2DZ+f for Re) level of theory taking int ...
This study is the first thorough method optimisation for accelerated solvent extraction (ASE) of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) from chemically dried compost. For PCBs, optimised solvent composition, temperatur ...
Toluene interaction with the catalysts consisting of 0.35, 0.62, 0.75 and 3.7 monolayers (ML) of VOx supported on anatase–titania, containing potassium, was studied by transient response techniques at 523–673 K. FT-Raman spectroscopy under dehydrated condi ...
The electrochem. promotion of the complete catalytic oxidn. of ethylene and toluene on RuO2Catalyst films deposited on Y2O3-stabilized-ZrO2 (YSZ) was studied at temps. 400 to 500 Deg. Anodic polarization (1.5 V), i.e. O2- supply from the YSZ support to the ...
