Tne bis-benzoxazinone 1 respond to nucleophilic attacks of either primary or secondary amines to give the benzamidoisophthalamide derivatives 2. The hitherto unknown N,N'-bis(2,2-benzoylhydrazine)isophthalamide 2d in reaction with CS2, NH4SCN and/ or KSCN afford the corresponding oxadiazolethione 4, triazolethione 5 and/ or the semi-carbazide derivative 6, respectively. Reaction of 2d with acetylacetone and/ or ethyl acetoacetate furnish the pyrazole 7 and/ or the pyrazolone derivative 8, respectively. The Shiff's base 10b and Schiff's base of the quinazolinone derivative 9c are obtained when 2d is condensed with p-anisaldehyde.
