Sažetak

The behavior of 2-phenylimidazo(l,2-b)pyridazines in some
electrophilic and nucleophilic subs.titution reactions has been
examined. It has been found that besides the expected electrophilic
substitution at position 3 of the imidazo-(1,2-b)pyridazine
ring, upon nitration a second nitro group enters the phenyl group
on para position as evident from an examination of the NMR
spectrum. Hydrazinolysis of a 3,6-dihalo derivative proceeded preferentially
at position 6.
