A new iodine heterocycle, 3, 6-dinitro-dibenzopyriodonium bisulfate(Ⅲa), prisms, m.p.217.5°(dec.), was found to be readily prepared in 86% yield by treating 4, 4'-dinitrodiphenylmethane with iodosyl sulfate, which was conveniently obtained by stirring a stoichiometric mixture of iodine and sodium iodate in concentrated sulfuric acid.
