چکیده
Compounds of the general formula (CH3NH3)„_i(CH3C6H4CH2NH3)2Pb„X3„+i, where X = I, Br, Cl and n= 1,2, 3,..., were prepared and characterized analytically and spectroscopically. Moreover, (CH3C6H4CH2NH3)2PbX4 and (C H ^N H jX C ^C e^C H zN H jhP b il? were charac terized by X-ray crystal structure analysis. Their optical absorption and photoluminescence spectra exhibit excitonic bands, even at room temperature.

Direct reactions between copperIJI) halides, thioacetamide (TAA) and 4,4′-bipyridine (4,4′-bpy) or pyrazine (pyz) in MeCN led to the formation of mixed ligand compounds [Cu2Cl2IJTAA)2IJ4,4′-bpy)]n (1), [Cu2X2IJTAA)4IJ4,4′-bpy)]·(4,4′-bpy) (X = Cl (2), Br (3) and I (4)) and [Cu2Cl2IJTAA)2IJpyz)]n (5), and the binuclear complex [Cu2I2IJTAA)4] (6). The formation of these compounds strongly depends...

Some N¬-acyl-N'-aryl thiourea derivatives 4(a-f) have been prepared by the reaction of acyl halides ammonium thiocyanate and aryl amines. The structures of synthesized compounds have been characterized by IR, 1HNMR spectral studies. The synthesized compounds 5(a-f) have been screened for antibacterial activity. The effect of the structure of the investigated compounds on the antibacterial activ...
متن کاملPalladium-catalyzed difluoromethylthiolation of heteroaryl bromides, iodides, triflates and aryl iodides
A palladium-catalyzed difluoromethylthiolation of heteroaryl halides and triflates under mild conditions was described. A vast range of heteroaryl halides such as pyridyl, quinolinyl, benzothiazolyl, thiophenyl, carbazolyl and pyazolyl halides could be difluoromethylthiolated efficiently, thus providing medicinal chemists with new tools for their search of new lead compounds for drug discovery....
متن کاملSynthesis and characterization of novel iminobenzoates with terminal pyrazine moieties
Apart from its numerous biological activities like antidiabetic, anti-inflammatory, antimicrobial, pyrazine moiety plays an important role in luminescent materials. Its role in luminescent materials is due to its highly electron deficient nature specially when it is in the centre along the mainstay of extended π-conjugated systems. Similarly, new liquid crystalline compounds are being made cons...
