Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 1078-61-1, Name is 3-(3,4-Dihydroxyphenyl)propionic acid, SMILES is O=C(O)CCC1=CC=C(O)C(O)=C1, in an article , author is Veisi, Hojat, once mentioned of 1078-61-1, Product Details of 1078-61-1.

Phenyl sulfonic acid functionalized mesoporous SBA-15 silica (SBA-15-Ph-SO3H) was prepared through the silanization of activated mesoporous SBA-15 with diphenyldichlorosilane (DPCS) followed by silylation and sulfonation, and characterized by XRD, FT-IR, nitrogen adsorption analyses, BET theory and TEM. The sulfonic acid groups anchored to the silica surface of the pore walls were resistant to leaching in organic and aqueous solutions under mild conditions. This catalyst was found to be a recyclable heterogeneous catalyst for the rapid and efficient synthesis of various 2H-indazolo[2,1-b]phthalazine-triones and triazolo [1,2-a]indazole-triones. Also, this silylated mesoporous material containing phenylsulfonic acid groups has a greater stability of the sulfonic acid surface toward water than that of silica sulfuric acid (SSA) and sulfonated SBA-15.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 1078-61-1, Name is 3-(3,4-Dihydroxyphenyl)propionic acid, SMILES is O=C(O)CCC1=CC=C(O)C(O)=C1, in an article , author is Bodman, Samantha E., once mentioned of 1078-61-1, Formula: https://www.ambeed.com/products/1078-61-1.html.

The reaction of ligands based on 3,6-di(2-pyridyl)pyridazine with symmetrical carbocyclic rings fused to the pyridazine ring; 7,10-di(2-pyridyl)-8,9-diazafluoranthene (L-1), 1,4-di(2-pyridyl)-6,7,8,9-tetrahydro-5H-cyclo-hepta[d]pyridazine (L-2), 1,4-di(2-pyridyl)-5,6,7,8-tetrahydro-phthalazine (L-3), 1,4-di(2-pyridyl)-6,7-dihydro-5H-cyclo-penta[d]pyridazine (L-4) with silver salts gave a series of complexes (1-7). Characterisation of these using single crystal X-ray structure determination clearly showed that the steric bulk of the carbocycle affects the degree to which pyridine groups remain co-planar with pyridizine, and hence their ability to chelate. The more hindered ligands L-1-L-3 form a mixture of bischelating and tetrabridging, while the least hindered (L-4) was able to chelate exclusively. In the case of L-4, the nature of the anion and solvent were also able to affect the outcome of the reaction, with tetrafluoroborate giving the first example of a 4,5-substituted 3,6-di(2-pyridyl) pyridazine ring forming a [2 x 2]-grid.

A new multifunctional and highly selective chemosensor 1 for Co2+ and Cu2+ was designed and synthesized. 1 could simultaneously detect both Co2+ and Cu2+ by changing its color from pale yellow to pink and to orange in a near-perfect aqueous solution. The binding modes of 1 to Co2+ and Cu2+ were determined to be a 2 : 1 complexation stoichiometry through Job’s plot, ESI-mass spectrometry analysis and H-1 NMR titration. The detection limits (1.5 and 2.1 mu M) of 1 for Co2+ and Cu2+ were lower than the DEP guidelines (1.7 mu M for Co2+) and the WHO guidelines (31.5 mu M for Cu2+) for drinking water. The chemosensor 1 could be used to quantify Co2+ and Cu2+ in water samples. Moreover, 1 could be used as a practical, visible colorimetric test kit for both Co2+ and Cu2+. The sensing mechanisms of Co2+ and Cu2+ by 1 were supported by theoretical calculations.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 1078-61-1, Name is 3-(3,4-Dihydroxyphenyl)propionic acid, SMILES is O=C(O)CCC1=CC=C(O)C(O)=C1, belongs to phthalazine compound.

Nano-organocatalyzed one-pot four-component reactions for the synthesis of phthalazine-trione/dione derivatives have been devised for the first time from easily accessible starting materials under solvent-free conditions. This methodology showed very good substrate scope and high degree of tolerance for a variety of aldehydes (including aliphatic and heteroaromatic aldehydes) and active methylene compounds. Moreover, the catalyst can be easily separated from the reaction mixture because of its highly paramagnetic nature, by using an external magnet, and can be reused in five more consecutive runs without much decrease in catalytic activities. Other significant advantages of this method are shorter reaction time, good yield, simple work-up procedure, easy catalyst handling etc.

Diiminoisoindoline (DII) is a crucial reagent for the synthesis of phthalocyanine as well as related macrocycles and chelates such as hemiporphyrazine and bis(iminopyridyl)isoindoline. In this report, we present the synthesis and characterization of four 1,3-diylideneisoindolines prepared via the reaction of several organic CH acids and DII. These orange or red compounds exhibit intense pi-pi* transitions in the UV visible region. The redox properties and electronic structures of all new compounds were investigated using cyclic voltammetry and density functional theory (DFT). The observed electrochemistry and UV-visible transitions are in good agreement with the DFT and time-dependent DFT calculations, which indicate that the HOMO is largely centered at the O=C-C-C=O fragments, and the lowest unoccupied molecular orbital is more extended onto the isoindoline unit.

The structure of the synthesized, new compounds were characterized by spectral data. The anti-proliferative activity on human breast cancer cell line MCF-7 of the synthesized compounds was determined. The results showed that six of the test compounds (3a, 3g, 3i, and 4a-c) displayed potent cytotoxic activity ranging from 1.4 to 2.3 mu mol.
