Nitrative Cleavage of 2, 2'-Dihydroxy-3, 3'-dimethyl 5, 5'-methylenedibenzoic Acid
Reactions of the title compound Cl J with nitric acid (d=1. 38) have been investigated in chloroform, carbon tetrachloride, nitromethane, methanol, and acetic acid. In every case, C 1] underwent facile nitrative cleavage and nitrodecarboxylation to yield 2-hydroxy-3-methy1-5nitrobenzoic acid C 2] as the major isolable product. Other products obtained include 4, 4'dihydroxy-3, 3'-dimethyl-5, 5'-dinitrodiphenylmethane C 3 D, 4-hydroxy-3-methyl-5-nitrobenzyl nitrate C 4 ), and 4,
