Abstract

Several workers, chief among them Kehrmann, a have shown that monosubstituted quinones (I, R's= halogen or alkyl) can be converted either into mono oximes or into dioximes, and that the mono oxime is the one whose formation involves the unhindered carbonyl group. Similarly, 9-disubstituted quinones give mono-or di-oximes. However, m- disubstituted quinones as well as tri-substituted quinones, lead only to monooximes, and ...
