Abstract

5, 6-Dichloro-5, 6-dihydro-1, 10-phenanthroline (2) was found as an additional product of 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 ...
