“…Subsequently the target compounds (17-21) were synthesised using 3 o A zeolite [16,17] as catalysts. 5(4H)oxazolones (7)(8)(9)(10)(11) were heated to reflux with various substituted aromatic amines (12)(13)(14)(15)(16) containing different electron donating and withdrawing groups is a solution of slight excess of pyridine with this catalyst. Further work up and chromatography over silica gel using hexane and ethyl acetate resulted in the final products.…”

A series of five new 1-(substituted phenyl)-2-phenyl-4-(substituted benzylidine)-imidazole-5-one derivatives (or) 5(4H)-imidazolones have been synthesised adopting 3 o A Zeolite as catalyst. These compounds were assayed for their antifungal activity on three different selected phytopathogens which disparately affects the Jowar crop (Sorghum Vulgare) of Poaceae family. Among the tested molecules, compound 18 exhibited potent inhibitory activity when compared to the Bavistine (Positive control).

A series of five new 1-(substituted phenyl)-2-phenyl-4-(substituted benzylidine)imidazole-5-one derivatives (or) 5(4H)-imidazolones have been synthesized adopting SiO2, Al2O3-90 and Y-faujasite (Y-H type) zeolite as catalysts. These compounds were assayed for their antifungal activity on three different selected phytopathogens which disparately affects the Jowar crop (Sorghum vulgare) of poaceae family. Among the screened target molecules, compound 18 exhibited potent inhibitory activity compared to the standard drug bavistine, which is worth for further investigation.

“…Oxazolone derivatives exhibit interesting photophysical and electrochemical properties and therefore, utilized as the promising materials for the electronic devices, biosensors, non-linear optical materials, and wide varieties of dyes [21][22][23][24][25]. The photophysical property is one of the important parameters of organic molecules for the potential applications in photonics and electronics [26,27].…”

“…Several reports are available on the absorption and emission studies of differently substituted oxazolone derivatives like Murthy et al studied the photophysical behavior of five new oxazolone derivatives, which showed an intense absorption at 350-480 nm with the emission maxima at 390-535 nm [28]. In another work, Murthy and co-workers performed the photophysical studies of 4-(4′-N,Ndimethylbenzylidene)-2-phenyloxazol-5-(4H)-one and reported the absorption and emission maxima at ~465 and ~522 nm, respectively [23]. Ozturk et al reported the synthesis and the photophysical studies of four different oxazolone derivatives, substituted with N-phenylaza-15-crown-5 moiety which showed an intense visible absorption and an emission maxima in the range of 467-524 nm and 496-689 nm, respectively [29].…”

The present study reports the two step synthesis of a novel oxazolone derivative, 4-((4,6-bis(4-((Z)-(5-oxo-2-phenyloxazol-4(5H)-ylidene) methyl)phenoxy)-1,3,5-triazin-2-yl) oxy) benzaldehyde (CBOZ (5)), containing two oxazolone ring substituted with central triazine nucleus in their structural framework. The structural and spectroscopic properties of synthesized CBOZ (5) were characterized by FTIR, 1HNMR, 13CNMR, and mass spectroscopic analysis. The UV-Vis absorption of CBOZ (5) showed a single absorption band at ~370 nm due to π-π* transition with the estimated energy gap of ~3.02 eV. Cyclic voltammetry analysis revealed that the synthesized CBOZ (5) obtained the HOMO and LUMO values of -5.87 eV and-2.85 eV, respectively. Density functional theory (DFT) studies were carried out to predict the electronic absorption spectra of CBOZ (5) and the obtained values were in excellent agreement with the experimental results.
