Studies of the acylarylnitrosamine reaction. I. The use of nitrosylsulfuric acid in the preparation of unsymmetrical biaryls

Abstract

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.
