- The Nitration of some 4-Alkylphenols; Acid-Catalysed Rearrangements of Some Polysubstituted 4-Alkyl-4-hydroxycyclohexa-2,5-dienones
-
The nitrations of 4-methyl (6a) and 4-ethyl (9a) tetrabromo phenols, and 4-methyl (6b) and 4-ethyl (9b) 2,3,5-tribromo-6-nitrophenols are described.The acid-catalysed rearrangements of 4-alkyl-4-hydroxycyclohexa-2,5-dienones (7a,b) and (8a,b) in concentrated sulfuric acid are described, and the effects of the nature of the C4-alkyl group and C6-substituent (Br or NO2) on the observed reactions are discussed.

- 13C Nuclear Magnetic Resonance Spectra of Some Bromo- and Methyl-substitued Cyclohexa-2,5-dienones
-
The 13C n.m.r. spectra of cyclohexa-2,5-dienones produced by bromination or nitration of a variety of methyl-substitued phenols are reported.Most of the signals have been assigned with the assistance of selective decoupling.Correlations of chemical shifts
