Reaction Steps
A mixture of 2 mmole of xanthene, 10 mole % of N-hydroxyphthalimide relative to xanthene, and 5 ml of benzonitrile was stirred for 20 hours at 100° C. under an oxygen atmosphere. The products in the reaction mixture were analyzed by gas chromatography, and, as a result, 9-oxoxanthene (yield not less than 99%) was formed.
