Pyrazolo[3,4‐ d ]pyridazines, isoxazolo[3,4‐ d ]pyridazines, azolo[1,5‐ a ]pyrimidines, azolo[5,1‐ c ]triazines, pyrazoles, and benzo[ b ][l,4]diazepine were synthesized from the appropriate hydrazonoyl halides, hydroximoyl halides, heterocyclic amines, diazotized heterocyclic amines, arenediazonium chlorides, and o ‐phenylenediamines with appropriate of sodium 3‐(5‐bromobenzofuran‐2‐yl)‐3‐oxoprop‐1‐en‐1‐olate or 1‐(5‐bromobenzofuran‐2‐yl)‐3‐(dimethylamino)prop‐2‐en‐1‐one. The newly synthesized compounds were elucidated by elemental analyses, spectral data, and alternative synthesis whenever possible.
