Conclusions

  1. 1.

    The conditions of azo-coupling of 2,6-dialkylphenols in aprotonic medium were developed.

     
  2. 2.

    The kinetics of the azo-coupling of 2,6-dialkylphenols with p-benzoquinone diazide was studied spectrophotometrically.

     
  3. 3.

    The reaction of azo-coupling proceeds through the step of formation of an intermediate quinolide compound, the decomposition of which determines the summary rate of the process.
