Excerpt from The Synthesis of Mono-Amino-Flavones, of Flavone-Azo-Beta-Napththol Dyes and of Other Flavone Derivatives: Dissertation Submitted in Partial Fulfillment of the Requirements, for the Degree of Doctor of Philosophy, in the Faculty of Pure Science of Columbia University
See structure I.duction of a mixture of mono-nitro - derivatives resulting from the nitration of ?avone. The isomeric nitro compounds were not isolated because they possessed too little difference of solubility in the solvents tried to give a satisfactory separation. The isolation of the individual amino-?avones, however, was effected by taking advantage of their differing basicity and solubilities.
The position of the amino group in each one of the three amino-?avones which were synthesized was determined by conversion of the amine, thru its diazonium compound, into the corresponding phenol.
