Carbamoylmethylphosphinoxide derivatives based on the triphenylmethane skeleton. Synthesis and extraction properties

Two different strategies were used to synthesize tri(2-alkoxy-5- nitrophenyl)methanes 6a,b. The X-ray structures of 6a and its precursor 5 show the molecules in a conformation with a syn-orientation of the nitro and alkoxy groups. Hydrogenation and acylat

Mechanism-Inspired Design of Bifunctional Catalysts for the Alternating Ring-Opening Copolymerization of Epoxides and Cyclic Anhydrides

Advances in catalysis have enabled the ring-opening copolymerization of epoxides and cyclic anhydrides to afford structurally and functionally diverse polyesters with controlled molecular weights and dispersities. However, the most common systems employ b

Preparation method of cycloalkylaminophenol intermediate (by machine translation)

The invention provides a preparation method, of a cycloalkylaminophenol intermediate. The method comprises the following steps: A) reacting an alkyl-substituted phenol, hexamethylenetetramine and acetic acid or a derivative thereof, obtaining first crude product; B) reacting the first crude product and the cycloalkylamine compound to obtain second crude product; C) reacting the second crude, the hydrogenated reducing agent in an alcohol solvent, and obtaining an aminophenol intermediate. The preparation method of the cycloalkylaminophenol intermediate is simple in process, mild in condition, and mild in condition. The prepared alkylaminophenol intermediate has good purity and yield, and is suitable for industrial production. (by machine translation)

Salicylaldehyde Hydrazones: Buttressing of Outer-Sphere Hydrogen-Bonding and Copper Extraction Properties

Salicylaldehyde hydrazones are weaker copper extractants than their oxime derivatives, which are used in hydrometallurgical processes to recover ～20% of the world's copper. Their strength, based on the extraction equilibrium constant Ke, can be increased by nearly three orders of magnitude by incorporating electron-withdrawing or hydrogen-bond acceptor groups (X) ortho to the phenolic OH group of the salicylaldehyde unit. Density functional theory calculations suggest that the effects of the 3-X substituents arise from a combination of their influence on the acidity of the phenol in the pH-dependent equilibrium, Cu2++2Lorg→[Cu(L-H)2]org+2H+, and on their ability to 'buttress' interligand hydrogen bonding by interacting with the hydrazone N-H donor group. X-ray crystal structure determination and computed structures indicate that in both the solid state and the gas phase, coordinated hydrazone groups are less planar than coordinated oximes and this has an adverse effect on intramolecular hydrogen-bond formation to the neighbouring phenolate oxygen atoms.

Synthesis and structural properties of novel calixarene analogues having Schiff base units

Novel calixarene analogues having Schiff base units have been synthesised by condensation reaction of the bisaldehyde with ophenylenediamines in the presence of boric acid. The present calixarene analogues form hydrogen bonds between imine nitrogen and ph

Bis-(2-benzylaminoethyl)-disulfides

It has been found that bis(2-benzylaminoethyl)-disulfides with the phenyl rings carrying various simple substituents, are highly effective anti-inflammatories and inhibit chemotaxis of human neutrophils.

Quinone Dehydrogenation. Oxidation of Benzylic Alcohols with 2,3-Dichloro-5,6-dicyanobenzoquinone

2,3-Dichloro-5,6-dicyanobenzoquinone (DDQ) reacts with primary and secondary aryl-substituted alcohols under mild conditions in dioxane solution to give the corresponding carbonyl compounds in high yields.In contrast to other oxidants, DDQ can be applied advantageously for the oxidation of hydroxyaryl-substituted alcohols.A mechanism involving participation of the phenolic hydroxyl group in the dehydrogenation reaction is discussed.Oxidations of hydroxyaryl-substituted alcohols by DDQ in methanolsolution resulting in the formation of benzoquinones by loss of the hydroxyaryl side chain are interpreted in terms of phenol oxidation.An example of a pyridine-catalyzed Smiles rearrangement of an o-hydroxy-substituted diphenyl ether is reported.
