1-(4-Chlorobutanoyl)-3-(3-chlorophenyl)thiourea

Condensation of thiohydrazide analogues with 4-bromo-3, 6-dichloropyridazine: an efficient rout to pyridazino[4, 3-e][1, 3, 4] thiadiazines

Abstract- Some new 3-(alkylsulfanyl)- 7-chloro-1-phenyl-1H-pyridazino [4,3-e][1,3,4]thiadiazine were synthesized  by treatment of the alkyl-2-phenylhydrazinecarbodithioates with 4-bromo-3,6-dichloropyridazine in alkaline acetonitril. Orientation of the reaction has been determined by X-Ray crystallography technique. The chlorine atom on the number 7 position of these products was repla...

3-(4-Bromo­anilino)-3-(4-chloro­phen­yl)-1-phenyl­propan-1-one

The asymmetric C atom in the title compound, C(21)H(17)BrClNO, is in a slightly distorted tetra-hedral environment and the NH unit adopts a gauche orientation with respect to the CO group. In the crystal, pairs of inter-molecular N-H⋯O hydrogen bonds form centrosymmetric dimers.

Condensation of thiohydrazide analogues with 4-bromo-3, 6-dichloropyridazine: an efficient rout to pyridazino[4, 3-e][1, 3, 4]thiadiazines.

Some new 3-(alkylsulfanyl)- 7-chloro-1-phenyl-1H-pyridazino [4,3-e][1,3,4]thiadiazine were synthesized  by treatment of the alkyl-2-phenylhydrazinecarbodithioates with 4-bromo-3,6-dichloropyridazine in alkaline acetonitril. Orientation of the reaction has been determined by X-Ray crystallography technique. The chlorine atom on the number 7 position of these products was replaced by secondary am...
