In a document, author is Mironov, Maxim A., introducing its new discovery. Quality Control of H-D-Phg-OH.

Multicomponent reactions between phthalazine, alkyl isocyanides, and 1,1-dicyanoalkenes in acetonitrile-water mixture produced high yields of substituted pyrrolo[2,1-a]phthalazines, which were converted upon treatment with 10% hydrochloric acid to pyrrolo[2,1-a]-phthalazines unsubstituted at position 1. As a result, a range of new pyrrolo[2,1-a]phthalazine derivatives have been synthesized by this one-pot approach.

The catalytic activity of four heterogeneous solid acid catalysts with magnetic core and sulfonic acid groups is evaluated and compared using one-pot three component synthesis of phthalazine-trione derivatives under solvent-free condition. The NiFe2O4 particles were selected as magnetic core, due to their enhanced chemical and magnetic stability. Furthermore, the desired products were obtained in excellent yields at short reaction times and environmentally friendly condition using the novel and reusable sulfonic acid grafted onto TiO2-coated nickel ferrite nanoparticles. This protocol avoids the use of expensive catalysts, toxic solvents and harsh reaction conditions.

A series of mononuclear gold(iii) complexes of the general formula [AuCl3(diazanaphthalene)], where diazanaphthalene is quinazoline (qz, 1), phthalazine (phtz, 2), 1,5-naphthyridine (1,5-naph, 3), 1,6-naphthyridine (1,6-naph, 4) or 1,8-naphthyridine (1,8-naph, 5), were prepared and fully characterized. The complexes 1-5 consist of discrete monomeric species with the Au(iii) cation in a square planar coordination geometry surrounded by three chloride anions and one diazanaphthalene ligand. Crystallographic studies indicate the presence of an extended 4 + 1 or 4 + 2 geometry around the square planar [AuCl3(diazanaphthalene)] center due to AuMIDLINE HORIZONTAL ELLIPSISCl and AuMIDLINE HORIZONTAL ELLIPSISN interactions. The crystal structures of these complexes are controlled by a variety of intermolecular interactions that utilize the amphiphilic properties of the coordinated chloride anions and involve C-H groups, pi-electrons, and an uncoordinated nitrogen atom of the diazanaphthalene ligand. The usual offset pi-stacking between the N-heteroaromatic ligands appears to be completely hindered between the 1,5-naph fragments and significantly weakened between the 1,6-naph and 1,8-naph in their respective complexes 3, 4 and 5, for which the average molecular polarizability (alpha) values are the lowest in the series. It is remarkable that the [AuCl3(benzodiazine)] complexes 1 and 2 form centrosymmetric crystals, but the [AuCl3(naphthyridine)] complexes 3-5 assemble into non-centrosymmetric aggregates, making them potential alternatives to the previously studied systems for application in various fields by taking advantage of their polarity.

Reference of 122-99-6, As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 122-99-6, Name is 2-Phenoxyethanol, SMILES is OCCOC1=CC=CC=C1, belongs to phthalazine compound. In a article, author is Yan, Xiaohui, introduce new discover of the category.

Solid-phase microextraction (SPME) coupled with thermal desorption-gas chromatography (TD-GC) has become a powerful analysis tool for volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) in water samples. However, water adsorption into polar microextraction phase is usually unavoidable during the extraction process, and the burst of large amounts of water vapour during thermal desorption will cause serious problems to GC separation and detectors. Pawliszyn’s group had demonstrated that the tens of micron-thick, defect-free polydimethylsiloxane (PDMS) coating could act as a perfect barrier for water adsorption and offer much better compatibility in complex matrices. However, the PDMS overcoat largely decreased the uptake rate of polar analytes into the inner sorbent. In order to quantify the effect of PDMS coating thickness on water adsorption amount and the extraction kinetics, ultrathin PDMS layer was used to coat the polar extraction phase with polyimide (PI) as a model in this work. It was surprising to find that the PDMS coating with the thickness less than one micron can decrease the water adsorption by 96%, while the extraction efficiency for polar analytes (phenolic compounds and nitroaromatic explosives) was decreased by less than 20% at the extraction time of 30 min. Moreover, the kinetic data showed that the thinner the PDMS coating was, the less the uptake rate of polar analytes into PI extraction phase decreased. Finally, polar poly (phthalazine ether sulfone ketone) (PPESK) extraction phase was also coated with ultrathin PDMS coating to verify the universality of the strategy. Generally, the water adsorption problem in polar SPME was overcome to a great extent, and the extraction efficiency of polar analytes was mainly preserved with this ultrathin PDMS coating, which could broaden the application of SPME in the environmental field.

Several Pd(II) complexes with unconventional pyridazine- and phthalazine-derived carbene ligands were synthesized via direct oxidative addition of Cl derivatives of the alkylated diazine heterocycles to Pd(0) species. The alkylated ligand precursors are readily prepared from commercial starting materials, and oxidative addition is regioselective. DFT calculations confirm that the thermodynamically favored products are formed. Four complexes (1-4) have been fully characterized, including by X-ray crystallography. Attractive intramolecular pi-pi stacking between the electron-poor N-alkylated diazine heterocycles and adjacent phenyl groups of the PPh3 coligands is revealed by the solid-state structures.
