TRANSFORMATIONS OF 1-AZIDO-2-ARYLOXYANTHRAQUINONES AND 3-ARYLOXYANTHRAISOXAZOL-6-ONES

Gornostaev, L. M.,Levdanskii, V. A.

, p. 1884 - 1890 (2007/10/02)

When heated, 1-azido-2-aryloxyanthraquinones undergo cyclization to 3-aryloxyanthraisoxazol-6-ones.As a result of thermolysis the latter are converted into 5,6-phthalylphenoxazines.The 5,6-phthalylphenoxazines are also obtained directly from 1-azido-2-aryloxyanthraquinones.Kinetic measurements showed that the conversion of the azides into 5,6-phthalylphenoxazines is a consecutive process involving the intermediate formation of 3-aryloxyanthraisoxazol-6-ones.
