Abstract
The basicities of 16 substituted azoxybenzenes have been measured by U.V. spectrophotometric method. The effects of substituents on the basicities are discussed in terms of Hammett's equation. The reaction constants, ρYX and ρXY, in a modified equation, log KXY/K∞=σXρXY+σYρYX, are 2.46±0.12 and 2.25±0.26 respectively. The validity of the equation is analysed by a statistical method, and the structure of the conjugate acid of the substituted azoxybenzenes is proposed.
