AbstractThe aminomethylation of 5-amino-1-naphthol (1) and 5-acetamido-1-naphthol (9) is examined. While the hydrogenolysis of the phenol Mannich bases derived from 1 cannot be accomplished, the derivatives of 9 react easily. The oxidation of the 2-methylphenol compounds 5 and 18 to the corresponding quinones may performed with Fremy's salt. The following transforming of the amino to the hydroxy group by nitrosylsulfuric acid succeeds with small yield only.

Nitrosylsulfuric Acid

Nitrosylsulfuric acid, which is very easy to prepare in a pure state and is quite stable at room temperature, has been found to be a very suitable reagent for the nitrosation of acylarylamines. The nitroso derivatives can be isolated easily, and on decomposition in benzene have yielded unsymmetrical biaryls in improved yields. Some of the nitrosations that could not be achieved earlier have now been accomplished successfully by this method.
