Behbahani, Farahnaz K.,Khademloo, Elham
, p. 1507 - 1510 (2014)
A fast, efficient and versatile route for the synthesis of 4,4-diaminotriarylmethanes is reported using N,N-dimethyl aniline and aryl aldehydes in presence of FePO4 under solvent-free condition at 100°C.
The novel two step synthesis of CuO/ZnO and CuO/CdO nanocatalysts for enhancement of catalytic activity
Kumaraguru, K.,Sankaran, A.
, (2020)
In the present investigation, Copper oxide (CuO)/Zinc oxide (ZnO) and CuO/cadmium oxide (CdO) nanocomposites (NCs) were fabricated by a simple two-step process involving co-precipitation technique and hydrothermal approach for the first time. The Powder X-ray Diffraction (PXRD) pattern demonstrates the existence of monoclinic, hexagonal and cubic phase structure of CuO/ZnO and CuO/CdO NCs. The absorption spectrum of the material was obtained via UV–Visible Spectroscopy and the band-gap value is calculated using Tauc's relation as 1.7 eV, 2.8 eV and 2.75 eV respectively for pure, CuO/ZnO and CuO/CdO NCs. The FESEM images gave the spherical and stone-like morphologies in the prepared CuO/ZnO and CuO/CdO NCs. At room temperature, CuO/ZnO and CuO/CdO NCs act as superior catalyst for the reduction of Rhodamine B (RhB) and Malachite Green (MG) dyes and degradation efficiency attained to be 77.26%, 73.15% for RhB and 79.82%, 74.69 for MG, respectively.
Silver-catalyzed tandem 5- And 6-endo-cyclizationsviaconcomitant yne-ol-imine activation: selective entry to 2-aryldihydrofuroquinolines
Das, Prasanta,Karmakar, Swastik,Kundu, Sandip
, p. 16112 - 16118 (2021/09/22)
A silver(i) catalyzed domino imination-intramolecular biheterocyclization-aromatization cascade has been developed to construct 2-aryl/-heteroaryl dihydrofuroquinolines in moderate to good yield using an aldehyde and unprotected 4-(2-aminophenyl)but-3-yn-1-ol as precursors. Sequential Ag-(i)-induced 5-endo-digcyclization of the yne-ol part and 6-endo-trigcyclization of a proposed Ag-bound imine, followed by aromatization, furnish the furoquinoline derivatives.
