In this study, series of ring-substituted 2-styrylquinazolin-4(3H)-one and 4-chloro-2-styrylquinazoline derivatives were prepared. The syntheses of the discussed compounds are presented. The compounds were analyzed by RP-HPLC to determine lipophilicity. They were tested for their inhibitory activity on photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts. Prima...
In the title compound, C(15)H(10)Cl(3)NO(2), an intra-molecular N-H⋯O hydrogen bond forms a six-membered ring and enforces an almost coplanar conformation for the acetamido group, the central benzene ring and the bridging carbonyl C-C(=O)-C group: the dihedral angles between the benzene ring and the acetamide and carbonyl C-C(=O)-C planes are 7.06 (11) and 7.17 (12)°, respectively. The dihedral...
The title dihaloaniline, C(6)H(5)ClIN, shows no significant hydrogen bonds nor the commonly observed I⋯I inter-actions in the crystal structure, although an amino group and an I atom are available for such contacts. The crystal structure is stabilized by weak inter-actions involving the amine functionality as donor group and N or halogen atoms as acceptors.
nano-zno was employed for the adsorption of 4c2np from aqueous solutions in batch equilibriumexperiments to investigate its adsorption properties. the quantity of 4c2np adsorbed onto nano- znosurface was measured by uv-vis spectrophotometer. the effects of contact time, adsorbent dose, ph, andinitial concentration of 4c2np were investigated. the adsorption found to be strongly influenced by all...
