Abstrakt: The reaction of 5,7-dinitroquinolin-8-ol with NaBH4 produces a reactive hydride σ-complex, the treatment of which with a solution of acetic acid gives 5,7-dinitro-5,6-dihydroquinolin-8-ol. The protonation of the acetone σ-complex of 5,7-dinitroquinolin-8-ol forms a mixture of the tautomers 5,7-dinitro-6-(2-oxopropyl)-6,7-dihydroquinoline-8(5H)-one and 5,7-dinitro-5,6-dihydro-6-(2-oxopropyl)quinolin-8-ol, with a predominance of the latter.
