Sažetak

The successful synthesis of perchloroimidazo(l,2-b)pyridazine1 prompted
us to investigate the possibility .of preparing chlorinated pyridopyridazines.
Although both parent bicyclic systems (I, II) are not expected to be susceptible to electrophilic substitution, pyrido(2,3-d)pyridazine, when brominated, formed primarily a complex which upon pyrolysis at 170- 180° is transformed into the 3-bromo derivative2.
