Abstract
Reaction of (2, 4, 5-trimethoxyphenyl)(2-hydroxyphenyl) methanone with ceric ammonium nitrate furnished the xanthone, 2, 3-dimethoxy-9 H-xanthen-9-one. Under the same conditions the related (1, 4-dimethoxynaphthalen-2-yl)(2-hydroxyphenyl) methanone resulted in the formation of 12a-methoxy-5 H-benzo [c] xanthenes 5, 7 (12a H)-dione. Other examples of this novel transformation are also outlined.
