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...

A facile synthetic approach to the π-expanded tetrathiafulvalene derivatives is described. The Suzuki reaction of 3,6-dichloropyridazine-fused tetrathiafulvalenes with phenyl boronic acid or biphenyl boronic acid gave a series of novel T-shaped organic π-conjugates. The electronic properties of the conjugates were studied experimentally by the combination of cyclic voltammetry and UV-vis spectr...
