The 5-(2-phenylhydrazono)-3,3-dimethylcyclohexanone (PHDMC) is synthesized by reacting 5,5-dimethylcyclohexane-1,3-dione with 2-phenylhydrazine. Synthesized PHDMC is polycrystalline with monoclinic space group, P2₁/a. Miller’s indices values for each diffraction peak in the X-ray diffraction spectrum are calculated. Thin films of PHDMC with different thickness values (0.83–1.247μm) are prepared by thermal evaporation technique and they exhibit amorphous structure. Different vibrational modes, observed in infrared spectra of the powder and thin films, were assigned to the molecular bonding structure of PHDMC compound. The optical properties of PHDMC thin films are investigated by measuring the optical transmittance and reflectance at the normal incidence of the light in the spectral range 200–2500nm. The refractive and absorption indices of the films are found to be independent of the film thickness …

New Synthetic Routes of Functionally substituted[1,2,4][1,5-a]Triazoloquinoline, Coumarinimine, Quinoline, Chromene, Quinazoline, Pyrazoloquinazoline and Benzotriazolotriazine …

SEVERAL new functionally [1,2,4]triazolo[1,5-a]quinoline-4- …… carbonitriles (8a-c) and [1,2,4] triazolo[1,5-a]quinoline-4-carbox-amides 12a,b were prepared from Nʹ-(5,5-dimethyl-3-oxocyclohexen-1-yl)benzohydrazide (5) and arylmethylene nitriles 2a-c and 2d,e, respactively.Reacting 2-oxo-3H-indol-3-ylidene malonic acid derivatives 3a,b with 5 afforded dioxospiro [3H-indole-3,4ʹ-quinoline]-3ʹ-carbonitrile (15) and 2- oxo-[1H] indol-3-ylcyanoacetate (17), respactively.Treating 5 with the enaminoester 18 gave hexahydro-7,7-dimethyl-2,5-dioxoquinolin-3-yl]benzamide (20). Coupling of 5 with the aryl diazonium salts and heteroaryl diazonium salts gave the hydrazones (21) and tetrahydro-[1,2,4]triazolo[5,1-c] [1,2,4] benzotriazine-6-ylidene)benzohydrazide (26
