On Mononitrohinokitiols

Abstract

The authors obtained a mononitro compound (II), m.p. 124°, and a trinitro compound (III), m. p. 122°, by the nitration of hinokitiol (I) in petroleum ether.2'a) This nitration, if carried out in glacial acetic acid, yields a dinitro compound (IV), m.p. 155°, and a mononitro compound (V) of dark red, oily substance, which gives water-insoluble, red Na-salt by sodium acetate.Upon standing for several days at low temperatures (about 5° C), a bright yellow mononitro compound (VI), m.p. 52-54° , separated out of (V), but neither (II) nor (III) was obtained by this reaction.
