Synthesis of imidazolyl-group-bearing 5,10,15,20-Tetrakis(.ALPHA.,.ALPHA.,.ALPHA.,.ALPHA.-o-pivalamidophenyl)porphyrinatoiron(II) derivatives.

Synthesis and Characterization of o-Carboranylthioether Derivatives

The reactions of the dithiolato-o-carborane salt (Et3NH)2(S2C2B10H10) (2) with alkyl halides BrCH2CH=CH2, BrCH2CH2CH2Cl and C6H5CH2Cl, afford the o-carboranyl-bisthioether derivatives 3a – c, which have been characterized by IR and NMR (1H, 13C, 11B) spectroscopy, mass spectrometry, and single-crystal X-ray diffraction (3c). The photoluminescent properties of the known compound 3c has been inve...

Synthesis of some imidazolyl-thioacetyl-pyrazolinone derivatives and their antinociceptive and anticancer activities.

In this study, some 4-(1,5-diarylimidazol-2-yl)thioacetyl-1-phenyl-2,3-dimethyl-3-pyrazoline-5-one derivatives were prepared by reacting 4-(2-chloroacetyl)-1-phenyl-2,3-dimethyl-3-pyrazoline-5-one and 2-mercapto-1, 5-diarylimidazole derivatives. The antinociceptive and anticancer activities of the compounds obtained were investigated. It was observed that some of the compounds, 2a, 2d, 2g, and ...

Synthesis and oxidation of triarylamine derivatives bearing hydrogen-bonding groups.

Hydrogen-bonding triarylamines, 4-(N,N-bis(4-methoxyphenyl)amino)benzoic acid (TPA1), 5-(N,N-bis(4-methoxyphenyl)amino)isophthalic acid (TPA2), and N-(4-(1H-benzimidazol-2-yl)phenyl)-N,N-bis(4-methoxyphenyl)amine (BImTPA), were synthesized as radical cation precursors. TPA1 and TPA2 are readily p-doped by AgSbF(6) to give highly persistent radical cations. Poor solid-state spin yields of the ra...

synthesis and antimicrobial activity of some new chalcones bearing n-substituted imidazolyl ring

Synthesis and characterization of some antifungal Oalkyl (O-aryl) trithiophosphato derivatives of 1,3,2- dioxaborinanes

Complexes of the type (OCH2C(CH3)2CH2OB)2S2P(S)OR (where R=Me,Et,Pri,Bui,Ph,CH2Ph) have beensynthesized by the reactions of 2-chloro-1,3,2-dioxaborinanes and potassium salt of O-alkyl (O-aryl)trithiophosphates in 2:1 molar ratio in refluxing benzene. The product are formed as white or light yellowcoloured monomeric solid, soluble in common organic solvents and exhibit high sensitivity towardsat...
