F. Farina et al., SYNTHESIS OF NAPHTOQUINONE MONOACETALS BY OXIDATION OF NAPHTHOLS WITH(DIATOXYIODO) BENZENE, Anales de quimica, 91(1-2), 1995, pp. 50-55
Oxidation of p-unsubstituted naphthols 1, 3-6 with 2 equivalents of (d
iacetoxyiodo)benzene in methanol or ethylene glycol gives the correspo
nding monoacetals of naphthoquinone 2, 7-13, in good yield. The oxidat
ion of the 8-hydroxiquinoline 14 in methanol or ethylene glycol is als
o reported.
