A novel, practical protocol for the aerobic direct C-H acetoxylation of arenes, employing a recyclable heterogeneous rhodium catalyst, is reported herein. The trifluoroacetoxylation of 2-amido-substituted anthracenes proceeded at the 9-position with exclusive regioselectivity. The oxidation of variously substituted anthracenes and other polycyclic aromatics with molecular oxygen as a terminal oxidant proceeded under mild conditions, providing products in good to excellent yields.
