reaction of 5-phenyl tetrazole with ethyl chloroacetate to form ethyl (5-phenyl-1h-tetrazol-1-yl) acetate (1). compound 1 react with hydrazine hydrate in ethanol yield 2-(5-phenyl-1h-tetrazol-1-yl) acetohydrazide (2). the condensation of (2) with various aldehydes yield the corresponding substituted n'-[-arylidene]-2-(5-phenyl-1h-tetrazol-1-yl) acetohydrazide (3a- j). the compounds obtaine...

In the present study, a series of benzothiazol derivatives 3a-l containing pyrazolo[3,4-d]pyrimidine moiety at the second position were synthesized and characterized by analytical and spectral data. The compounds were tested for their in vitro antimicrobial activity. Compounds 1-(1,3-benzothiazol-2- yl)-3-methyl-4-phenyl-1H-pyrazolo[3,4-d]pyrimidine (3a), 1- (1,3-benzothiazol-2-yl)-4-(4-chlorop...

The design of an efficient pure blue emitter to achieve stable, long operating organic light-emitting diode (OLED) devices still poses a significant challenge. Although through phosphorescence and thermally activated delayed fluorescence concepts, stable monochrome green red OLEDs can be realized, the has been All efforts so far have resulted in severe efficiency roll-off limited device lifetim...

In the title compound, C(27)H(26)P(2)S, the P-C-P angle is 114.33 (13)°. The bond distances are longer and the bond angles are smaller at the P atom bonded to the o-tolyl groups owing to the presence of a lone pair of electrons. One phenyl ring is disordered over three sites [occupancies 0.317 (8), 0.250 (8), and 0.433 (6)] and the other phenyl ring is disordered over two sites [occupancies 0.8...

Present work describes the Synthesis of 3-(3-substituted-1H-indon-1-yl)-2-phenylquinoline-4carboxylic acid derivatives by Pfitzinger reaction of isatin with 2(1H-indol-1-yl)-1-phenyl ethanone and 1-phenyl-2-[-3-(substituted)-1-H-indole-1-yl] ethanone. The structures of all the compounds are established by elemental analysis, IR, H NMR and Mass spectral data. These compounds possess excellent an...
