Abstract
Alkylpyrocatechols are dealkylated by AlBr3 in CH2Br2 The formation of stable carbenium ions (tert-butyl, methylcyclopentyl, and 1-adamantyl ) was detected by H-1 NMR spectroscopy. Pyrogallol and 2,3-dihydroxyna phthalene are coordinated with ALBr(3) in the tautomeric keto form, an d 2-mercapto-4-methylphenol forms a complex in the hydroxy form.
