HOF·CH3CN, a very efficient oxygen-transfer agent, made readily from F2, H2O, and CH3CN, was reacted with various 1,10-phenanthroline derivatives to form the corresponding N,N‘-dioxides in good yields and short reaction times.

the hypochlorous acid action on 1,10-phenanthroline. When treated with MCPBA the product of the chlorine addition yielded a corresponding di-N-oxide 3, which readily lost hydrogen chloride under the influence of sodium isopropoxide. The resulting monchloro di-N-oxide 5 molecules (assumed to be flat) revealed a satisfactory stability unless the neutral or basic solution was made acidic.
