in the present work, highly efficient oxidation of sulfides catalyzed by moo2(acac)2 supported on multi-wall carbon nanotubes, mwcnts, modified with 1,2-diaminobenzene (dab) and 2-aminophenol (ap), at room temperature are reported. the effects of various parameters such as reaction time, solvent, catalyst amount, oxidant, etc, were studied. these heterogenized catalysts showed high activity in ...

The influence of chelate and mini-chelate effects on sulfate binding was explored for six amide-, amide/amine-, urea-, and urea/amine-based ligands. Two of the urea-based hosts were selective for SO4(2-) in water-mixed DMSO-d6 systems. Results indicated that the mini-chelate effect provided by a single urea group with two NH binding sites appears to provide enhanced binding over two amide group...

The title compound, [Mn(C(18)H(18)N(2)O(4))(C(7)H(5)O(3))(H(2)O)], was synthesized by a template reaction of ethane-1,2-diamine and 3-methoxy-salicylaldehyde in presence of manganese(II) 4-hydroxy-benzoate. The Jahn-Teller-distorted manganese(III) centre has an octa-hedral geometry. Extensive O-H⋯O hydrogen-bonding inter-actions generate a two-dimensional sheet structure parallel to (103).

Ga2O3 thin films were fabricated by spray pyrolysis method using gallium acetylacetonate as source material and water oxidizer. The annealed at 450°C for 60 minutes in argon atmosphere. X-ray photoelectron spectroscopy (XPS) depth profile studies carried out to analyze the stoichiometry composition of sprayed as-deposited films. Surface layers inner found nearly stoichiometric.

Stabilising C–Cl(lone-pair)⋯π(chelate ring) interactions are described.

A survey of delocalised C–I??(chelate ring) interactions is presented.
