Suryawanshi, Manjusha published the artcileSynthesis, characterization and photophysical properties of novel thiazole substituted pyridine derivatives, Name: Picolinonitrile, the main research area is pyridylthiazole preparation photophys property.

Three series of isomeric 2-pyridyl 4-aryl thiazoles were synthesized by reacting 2/3/4-pyridine thioamides derived from the corresponding nitriles with various 4-substituted phenacyl bromides using Hantzsch thiazole synthesis. Amongst the three isomeric series, 2-pyridyl and 4-pyridyl isomers are found to exhibit better photophys. properties than 3-pyridyl series. 4-Pyridyl isomer with methoxy substituent on Ph ring is found to exhibit high luminescence quantum yield. The relationship between the structure and the photophys. properties have been studied using DFT calculations

Yadav, Kumar Karitkey published the artcileCopper(II) phthalocyanine as an efficient and versatile catalyst for click reactions at room temperature, Recommanded Product: Phthalonitrile, the main research area is copper phthalocyanine catalyst benzyl halide one pot click reaction.

Herein, we report the efficient synthesis of copper(II) phthalocyanines in the presence of DBU as a strong base. These synthesized copper(II) phthalocyanines are utilized as a catalyst for the click reactions of sensitive compounds including metal-free porphyrins under mild reaction conditions at room temperature Further, we have developed a one-pot procedure for the click reactions of benzyl halides with different alkynes in good to excellent yields. The reaction proceeds at room temperature to 40°C and gives 83-99% of products. The reactions are carried out in DMSO solvent. The present reaction condition offers copper(II) phthalocyanines as an efficient and convenient catalyst for different electron-rich and electron-deficient substrates including macrocyclic compounds Electron-deficient substrates and less steric substrates provide a better result. The catalyst is easily separated from the reaction by a simple filtration technique and is reused up to 5 times without significant loss of its catalytic activity.

Meesa, Siddi Ramulu published the artcileCatalyst and solvent switched divergent C-H functionalization: oxidative annulation of N-aryl substituted quinazolin-4-amine with alkynes, SDS of cas: 1885-29-6, the main research area is indolequinazoline pyridoquinazoline preparation regio chemoselective; aryl quinazolinamine internal alkyne oxidative annulation.

The development of site-selective C-H functionalizations/annulations is one of the most challenging practices in synthetic organic chem. particularly for substrates bearing several similarly reactive C-H bonds. Herein, authors describe catalyst and solvent controlled ortho/peri site-selective oxidative annulation of C-H bonds of N-aryl substituted quinazolin-4-amines with internal alkynes. The ortho C-H selective annulation was observed using Pd-catalyst in DMF to give indole-quinazoline derivatives I (R1 = H, 7-Cl, 6,7-di-OMe; R2 = H, 4-Me, 4-OMe, 4-Cl,etc.; R3 = R4 = Ph, 4-MeC6H4, 2-thienyl, etc.), while, Ru-catalyst in PEG-400 favored the peri C-H bond annulation exclusively to furnish pyrido-quinazoline derivs II.

Bilgicli, Hayriye Genc published the artcileComposites of palladium nanoparticles and graphene oxide as a highly active and reusable catalyst for the hydrogenation of nitroarenes, Name: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is graphene oxide supported palladium nanoparticle preparation surface structure; nitrobenzene supported palladium nanocatalyst transfer hydrogenation green chem; aniline preparation.

The composite of palladium nanoparticles and graphene oxide (CPG) was synthesized by a facile and very efficient method that provided chem. selectivity and high catalytic activity. The synthesized CPG was characterized by several techniques such as transmission and high-resolution electron microscopy (TEM and HR-TEM), X-ray diffraction (XRD), Raman spectroscopy and Photoelectron spectroscopy (XPS). CPG was tested for selective reduction of nitroarenes at room temperature After the addition of CPG to the reaction media, catalytic performances were depended upon the cooperative effect of hydrogen activation with Pd nanoparticles, where the lack of electrons favors an excellent performance. Nitroarenes can be bound to the energetically preferred adsorption site for the nitro group in elec. enriched graphene oxide. In addition, the Pd nanoparticles transfer electrons to the graphene oxide which increased the functions of metal and carbon support. CPG exhibited both chemoprotective and high catalytic performance for hydrogenation of nitroarenes at room temperature Aniline derivatives were obtained with high yields under mild conditions and a practical catalytic system was developed by the use of CPG.

Saikia, Rakhee published the artcileRevisiting the synthesis of aryl nitriles: a pivotal role of CAN, Formula: C7H6N2, the main research area is nitrile aryl preparation; aryl iodide or bromide CAN cyanation catalyst copper trifluoromethanesulfonate.

Facilitated by the dual role of ceric ammonium nitrate (CAN), herein a cost-effective approach for the cyanation of aryl iodides/bromides with CAN-DMF as an addition to the existing pool of combined cyanation sources was reported. In addition to being an oxidant, CAN acted as a source of nitrogen in our protocol. The reaction was catalyzed by a readily available Cu(II) salt and the ability of CAN to generate ammonia in the reaction medium was utilized to eliminate the addnl. requirement of a nitrogen source, ligand, additive or toxic reagents. The mechanistic study suggested an evolution of CN- leading to the synthesis of a variety of aryl nitriles ArCN [Ar = Ph, 4-OHC6H4, 4-H2NC6H4, etc.] in moderate to good yields. The proposed mechanism was supported by a series of control reactions and labeling experiments
