unsymmetric functionalizedtriarylmethanols. Both reactions proceed smoothly in trifluoroacetic acid in the presence of an inexpensive oxidant (manganese dioxide or potassium persulfate) and a catalytic amount of palladium diacetate to give a range of functionalizedtriarylmethanols in moderate to good yields and with extremely high regioselectivity. The two unprecedented reactions involve tandem formation
