conditions has been achieved to furnish a variety of carbonyl functionalized 2-aroylimidazoles in moderate to good yields. The obtained products could be selectively transformed to the corresponding phthalazines and phthalazin-1(2H)-ones with hydrazine hydrate as the cyclization partner under different reaction temperature and construct an array of structurally diverse nitrogen-containing heterocycles.
