Phenol–dienone Rearrangement in the Reactions of Phenols

Abstract: The paper presents a combination of theoretical and experimental results which show that the sustainment phase of a driven Reversed-Field Pinch (RFP) configuration is not fundamentally limited in time by toroidal field diffusion. Driven ZT-40M discharges where the external poloidal voltage circuit does not directly maintain toroidal field reversal are examined. Flux measurements on slowly rising current discharges clearly show that a toroidal flux regeneration mechanism (referred to as the 'dynamo-effect') mus… Show more

“…Similar methods of preparation of these compounds were also described by Ershov and Zlobina (1963), Ershov, Volodkin, andBogdanov (1963), andWaring (1966). An interesting nitration of trialkylphenols is presented in Ershov and Zlobina (1964) in which a saturated aqueous solution of NaNO2 was used instead of nitric acid.…”

“…(ii) Values of ' J involving the methyl groups (Tables 3-5). The values for the couplings within the 2-methyl group (Table 3) cover the range 128.9-131.0 Hz, and are slightly lower for those compounds (l), (3), and (5) having adjacent hydrogen than for the remainder with adjacent bromine.…”

“…Thus for compounds in which R is methyl and E is nitro, the conversion shown in equation ( 2) is easily accomplished. When both R and E can be detached as nucleophiles, such dienones are readily converted into quinones [equation (3)]. Little is known about the mechanism of these displacements.…”
