A detailed inspection of phenolic oxidation products derived from the o,o'-dihalogenated cresol derivatives (1a - 1e) indicated that the bromo and chloro substituents promoted the oxidation leading to the corresponding diaryl ethers, whereas the iodo derivatives provided the diaryls. Selective reduction of 6d and its tyrosine derivative afforded the corresponding diaryl ethers carrying two chlorine atoms (14, 15). Interpretation of the selectivity of the phenolic oxidation was attempted by employing theoretical calculations.
Regioselective Alkylation of Anthrahydroquinone and Anthrone in Water with Quinonemethides and Other Alkylating Agents

Antrahydroquinone (AHQ) and anthrone are alkylated in the C10 position by quinonemethides, generated in situ from p-acetoxybenzyl chlorides, to give adducts 13-15, 24, 25, 28, 29, and 32.Aqueous alkylations of AHQ with methyl vinyl ketone, cinnamaldehyde, and benzyl chloride also produces C10-substituted 10-hydroxyanthrones.Simple ketones and aldehydes do not, however, alkylate AHQ in aqueous alkali.
