Syntheses and Ultraviolet Spectra of Aromatic Azo Compounds. I. Bromo-methylazobenzenes

Abstract

Abstract 1) Twelve bromo-methylazobenzenes have been synthesized by the reactions of Grignard reagents with zinc chloride double salts of diazonium compounds. Ten of them are new compounds. 2) The ultraviolet absorption spectra of bromo-methylazobenzenes have been measured and some regularities of the absorption maxima have been observed in them.
