The reactions of palladium(II) salts with 2-hydroxyacetophenone N(3)-propylthiosemicarbazone, H2Ap3Pr, are described. The synthesis and spectral characterization of a new triangular, trinuclear palladium(II) complex with the dianion, Ap3Pr2−, are reported. The X-ray crystal structure determinati...
The paper presents the conformational, vibrational and hydrogen bond characteristics of 5-methyl-3-nitro-2-hydroxyacetophenone studied with the combined matrix-isolation FT-IR spectroscopic and theoretical (DFT/B3LYP/6-31++G∗∗) technique. Theoretical calculations predict three stable conformatio...
A simple one-pot synthesis of 3-cyano-4-benzopyrones directly from 2-hydroxyacetophenones using mild conditions is reported herein.
A bishydrazone was obtained by the condensation of isatin monohydrazone with 2-hydroxyacetophenone, which formed a series of complexes with manganese(II), cobalt(II), nickel(II), copper(II) and zinc(II). The ligand and the metal complexes were characterized on the basis of elemental analysis, mo...
Solid–liquid equilibria (SLE) for three binary mixtures of N-phenylacetamide with 4-aminoacetophenone, 3-hydroxyacetophenone and 4-hydroxyacetophenone were measured using differential scanning calorimetry (DSC). Simple eutectic behaviors for all three systems were observed. The Wilson and UNIFA...
Standard molar enthalpy of vapourisation of 2'-hydroxyacetophenone and standard molar enthalpies of sublimation of 3'-hydroxyacetophenone and 4'-hydroxyacetophenone were obtained from the temperature dependence of vapour pressure measured by the transpiration method. Enthalpy of f...
A new AB2 type building block for synthesis of dendritic compounds is made starting from Michael addition of 2 equiv of 3-hydroxyacetophenone to acrylate, followed by decarboxylation and deprotection of either carboxyl or hydroxyl protecting groups. [G1]–[G4] dendrons and [G2] dendrimer were sy...
This paper shows Fourier-transform Raman (FT⬜RS) and surface-enhanced Raman spectroscopy (SERS) studies of three α-aminophosphinic acid derivatives of pyridine: [(butylamino)(pyridin-2-yl)methyl]phenylphosphinic acid (α-PyNH), [(butylamino)(pyridin-3-yl)methyl]phenylphosphinic acid (β-PyNH), ...
The complete set of NMR parameters for 17O enriched phenylphosphinic acid C6H5HP∗O(∗OH) is calculated from first principles by using the Gauge Including Projected Augmented Wave (GIPAW) approach [C.J. Pickard, F. Mauri, All-electron magnetic response with pseudopotentials: NMR chemical shifts, P...
A novel amphiphilic phosphorus-containing polymer was prepared by RAFT polymerization of 3-[2-(acryloyloxy)ethoxy]-3-oxopropyl(phenyl) phosphinic acid (AOPA). The monomer was first synthesized by esterification of 3-[hydroxy(phenyl)phosphoryl]propanoic acid and 2-hydroxyethyl acrylate, and then ...
A novel adsorbent benzoimidazol-2-yl-phenylphosphinic acid/aminosilica adsorbent (BImPhP(O)(OH)/SiO2NH2) was prepared by carbonyldiimidazole-mediated coupling of aminosilica with 1-carboxymethylbenzoimidazol-2-yl-phenylphosphinic acid. It was obtained through direct phosphorylation of 1-cyanomet...
Equilibria in the Cu2+–H4L1 and Cu2+–H4L2 systems, where H4L1 is 1,4,7,10-tetraaza-cyclododecane-1,4,7,10-tetrayl-tetramethylene-tetrakis(phenylphosphinic acid) and H4L2 is 1,4,8,11-tetraaza-cyclotetradecane-1,4,8,11-tetrayl-tetramethylene-tetrakis(phenylphosphinic acid), were investigated by ...
The ion-exchange/complexing properties of the resins containing various substituted phenylphosphinic acid ligands towards indium and gallium cations were investigated. Uptake of the above-mentioned cations was done on the resins in acid and ester forms, at different concentration of acid and in ...
A new extractant, [N,N-di(2-ethylhexyl)amino]methylphenylphosphinic acid (DEAPP), was synthesized to develop the mutual separation techniques of In(III), Ga(III) and Zn(II). The extraction selectivity for In(III), Ga(III) and Zn(II) with DEAPP was higher than that of the commercial phosphorus ac...
Novel, functional resins, containing variously substituted phenylphosphinic acid ligands, have been obtained via the Michael reaction. Reaction has been carried out on phenylphosphinic acid resin crosslinked with 2 wt.% of divinylbenzene using the following electrophiles: methyl chloroformate, e...
Functionalized resins, containing substituted phenylphosphinic acid ligands, were obtained by the reaction of styrene–divinylbenzene copolymer (2 wt.% of crosslinker, expanded gel structure) bearing phenylphosphinic acid groups with trimethylchlorosilane and then with an appropriate electrophil...
Functionalised phenylphosphinic acid derivatives have been synthesised by addition of bis(trimethylsilyl)phenylphosphonite 2 to a series of electrophiles.
