Hazarika, Shikharani published the artcileSilica supported spinel structured cobalt ferrite multifunctional nanocatalyst for hydration of nitriles and oxidative decarboxylation of phenylacetic acids, Application In Synthesis of 1885-29-6, the main research area is aryl aldehyde preparation green chem; phenyl acetic acid oxidative decarboxylation silica support ferrite nanocatalyst; amide preparation green chem; nitrile hydration silica support cobalt ferrite nanocatalyst.

The silica-supported cobalt ferrite spinel nanocatalyst has been successfully synthesized by the coprecipitation method and extensively characterized by FTIR, XRD, SEM-EDX, TEM, BET, VSM, XPS, TGA, and ICP-AES anal. The bands observed at 3435 cm-1 (μOH of Si-OH) and 1637 cm-1 (γOH of Si-OH) in the FTIR spectrum of the as-synthesized nanocatalyst unambiguously tell the presence of silica support. Moreover, a very weak intensity and a medium intensity peak at 683 cm-1 and 463 cm-1 suggested intrinsic stretching vibrations of Fe-O and Co-O of cobalt ferrite, resp. The XRD pattern confirms the formation of CoFe2O4 spinel. The average crystallite size was found to be 5.4 nm as calculated by using the Debye-Scherrer equation based on the (220) plane while the average particle size was found to be 5.08 nm from TEM anal. The crystalline nature of the nanocomposite was confirmed by the SAED pattern. The successful incorporation of CoFe2O4 on the surface of silica was established by the BET surface area measurements. The silica-supported cobalt ferrite nanocatalyst has been explored as a heterogeneous multifunctional catalyst for hydration of nitriles RCN (R = Ph, pyridin-3-yl, 4-cyanobutyl, etc.) and oxidative decarboxylation of phenylacetic acids R1CH2C(O)OH (R1 = Ph, 2-hydroxynaphthalen-1-yl, 2,5-dimethoxyphenyl, etc.) as well under mild reaction conditions with moderate to excellent isolated yield of the desired products (60-99%). The catalyst was magnetically recoverable within a time frame of ~90 s and reusable up to the fifth catalytic cycle without profound loss of activity. A magnetic hysteresis study was performed to elucidate the magnetic behavior of the catalyst. The saturation magnetization value of 39.785 emu/g with a coercivity value of 110.87 Oe and saturation remanence value of 5.185 emu/g clearly indicated the presence of a ferromagnetic component in the material.

Potikha, L. M. published the artcileCondensed isoquinolines. Part 21. Condensation of o-bromomethylphenylacetonitrile with substituted anthranilic acids, Recommanded Product: 2-(2-(Bromomethyl)phenyl)acetonitrile, the main research area is bromomethylbenzeneacetonitrile anthranilate cyclocondensation; isoquinoquinazolinone hydro preparation tautomerism.

The reaction of substituted anthranilic acids and esters with ortho-bromomethylphenylacetonitrile gives 2,3-disubstituted 7,12-dihydro-5H-isoquino[2,3-a]quinazolin-5-one hydrobromides. It was found that 7,12-dihydro-5H-isoquino[2,3-a]quinazolin-5-ones can exist in the two tautomeric imine and enamine forms. The tautomeric equilibrium position depends on the nature and position of the substituent in the quinazoline fragment. The borohydride reduction, oxidation, and reaction of the 7,12-dihydro-5H-isoquino[2,3-a]quinazolin-5-ones with electrophilic reagents was studied.

Vishwakarma, Niraj K. published the artcileConverting CO2 into heterocyclic compounds under accelerated performance through Fe3O4-grafted ionic liquid catalysts, Safety of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is heterocyclic compound preparation ferric oxide grafted ionic liquid catalyst.

Solid supported catalysts such as amines are in high demand for the chem. fixation of CO2 into commodity chems. Here, we demonstrate an accelerated platform for 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU)-ionic liquid (IL) catalyzed CO2 fixation via the grafting of DBU-ILs over magnetically separable Fe3O4 nanoparticles (MNPs). The DBU-ILs were covalently immobilized over Fe3O4 MNPs utilizing the thio-ene reaction of allyl-DBU with -SH modified Fe3O4 MNPs. The DBU-IL-grafted Fe3O4 (Fe3O4@DBU-ILs) materials were characterized by Fourier-transform IR spectroscopy, field-emission SEM, transmission electron microscopy, XPS, thermogravimetric anal. and vibrating-sample magnetometry. TEM revealed that the MNPs have a spherical structure with a particle size of 12-20 nm. VSM showed the gradual decrease in magnetization after stepwise grafting from Fe3O4 to Fe3O4@DBU-ILs. The efficacy of the two different Fe3O4@DBU-ILs, Fe3O4@[HDBU+][TFE-] and Fe3O4@[HDBU+][AcO-] prepared by neutralization of Fe3O4@DBU with 2,2,2-trifluoroethanol (TFE) and acetic acid (AcOH), was investigated by simultaneous fixation of CO2 into the important heterocyclic compounds quinazoline-2,4(1H,3H)-dione and benzimidazolone. This approach shows excellent recyclability with a nominal decrease (2-3%) in product yields after each cycle. In particular, the energy-dispersive X-ray spectroscopy mapping of Fe3O4@[HDBU+][TFE-] used for five cycles demonstrated significant leaching of TFE. Interestingly, after retreatment with TFE, Fe3O4@[HDBU+][TFE-] showed a similar yield to that of a fresh catalyst.
