“…2 Moreover, 2,3-dihyroquinazolinones are associated with several important biological activities such as anti-cancer, 3 anti-inflammation, 4 anti-bacterial, 5 anti-virus, 6 anti-tuberculosis, 7 anti-malarial, 8 anti-hypertensive, 9 anti-obesity, anti-psychotic, and anti-diabetes 10 . In this context, several synthetic methodologies have been developed employing metal-salts such as SmI 2 , 11 Ru-salts, 12 CuCl 2 , 13 SnCl 2 , 14 Sc(OTf) 3 , 15 ZnCl 2 , 16 [CpIrCl 2 ] 2 , 17 Pd(OAc) 2 , 18 CuO, 19 [Zr(DS) 4 ], 20 Ga(OTf) 3 , 21 TiCl 4 , 22 KAl(SO 4 ) 2 Á12H 2 O, 23a Al(H 2 PO 4 ) 3 , 23b [Ce(NH 4 ) 2 Á(NO 3 ) 6 ], 24 and metal nano-particles 25 of Co, Cu, Ag, In, La and Fe. Transition metals are expensive, unstable and often produce a considerable amount of metal wastes.…”

An efficient protocol has been developed for the synthesis of 2,3dihydroquinazolinone compounds from anthranilamide and aldehydes or ketones via ionic liquid catalyzed cyclization reaction. The reaction features high efficiency, shorter reaction duration, mild reaction conditions and inexpensive reagents. The catalyst was recovered and reused. The recyclability of ionic liquid resulted excellent yields of product without loss of any catalytic activity.This article described an efficient protocol for the syntheses of 2,3-dihydroquinazolinones. The synthetic utility of this methodology has been demonstrated with 30 different substrates. The reaction showed good functional group tolerance and high levels of catalytic activity.

“…The comparative advantage offer by composite coating over ordinary Zn coating makes them attractive. Binary Zn based composite coating exhibits superior surface properties [16][17][18]. Kumar and Venkatesha [19] studied the fabrication and electrochemical corrosion behaviour of ZnTiO2 composite and concluded that the incorporated TiO2 nanoparticles enhanced the compactness, microstructure and topography compared to pure Zn coating.…”

Composite coatings of Zn-Al6O13Si2 and Zn-Al6O13Si2-ZrO2 were electroplated on mild steel from Zn 2+ ions bath and homogeneously dispersed nano Al6O13Si2-ZrO2 particulates were achieved. The corrosion resistance characteristics of the deposited coatings were evaluated by linear polarization method. The microstructural properties of the multilayer produce coatings were examined by scanning electron microscope equipped with energy dispersive spectrometer, X-ray diffraction and atomic force microscope. The thermal deformation were observed in 250 ºC for 4 h and mechanical properties of the composite coatings were investigated using diamond base Dura scan microhardness tester. From the observed results, it was shown that the incorporation of particles into the electrolyte change the microstructure characteristics of developed composite and improved drastically the thermomechanical performance of the coatings.
