1,1-Disubstituted-3-(2-phenyl-3H-quinazolin-4-ylidene)thioureas (8) were synthesized in a one pot reaction of N-(2-cyanophenyl)benzimidoyl isothicyanate (3) with secondary amines. The products underwent transamination reactions. Compounds 8a-8g were...

1-substituted-3-(2-phenylquinazolin-4-yl) thioureas (7) were produced by an intramolecular cycloaddition reaction of 1-substitued-3-[(2-cyanophenylimino) phenylmethyl] thioureas (3). These compounds in turn were prepared by the reaction of N-(2-cyano...

Many compounds containing a -CONH- group display photosynthesis inhibiting activity. Based on this structural feature, a group of anilides of 2-alkylthio-(1b-4f) or 2-chloro-6-alkylthio-4-pyridinecarboxylic acids (5a-6c) was synthesised. The prepared...

Nitrophenols can be obtained in moderate to high yields using a combination of Mg(HSO₄)₂ or NaHSO₄.H₂O, NaNO₃ and wet SiO₂ in dichloromethane at room temperature.

Novel 1-[6-(p-tolyl) pyridazin-3-yl]pyrazole-o-aminonitriles (3a-c) were formed using 3-hydrazino-6-(p-tolyl)pyridazine (2) and ketene S,S-acetals (1a), S,Nacetals (1b) or tetracyanoethylene (1c). The pyrazole-o-aminonitriles (3a-c) were in turn used...

The electrochemical oxidation of bromide in the presence of 1,3-indandione (1) in water/acetic acid and methanol/acetic acid mixtures has been studied by cyclic voltammetry and controlled-potential coulometry. The results indicate the participation o...
