o‐Monobromoacetylacylphenones, 3a and 3b reacted with hydroxylamine or hydrazine hydrate to produce heterocycles, 2,3‐benzoxazine or phthalazine derivatives. The reaction of bromoacetyl group of 3a and 3b with several thioamides afforded thiazole derivatives in high yields. Whereas o‐dibromoacetyl‐benzophenoe 2a reacted with aniline or cyclohexylamine to produce non‐heterocycles, 2‐substituted‐iminophenylindanones and the mechanism for the formation of these non‐heterocycles is proposed.
