MECHANISM OF AZO COUPLING. V. KINETICS OF AZO COUPLING WITH HYDROXYSULFONATONAPHTHALENES

Luchkevich, E. R.,Bagal, I. L.,El'tsov, A. V.

, p. 1553 - 1560 (2007/10/02)

The formation of significant amounts of intermediate product not lying in the path of the reaction was demonstrated with the data on the kinetics of azo coupling of benzenediazonium cations with hydroxysulfonatonaphthalenes.It was hypothesized that this product is an O-azo ether.
