Direct Acetoxylation and Etherification of Anilides Using Phenyliodine Bis(tri-fluoroacetate). — Reaction of a wide variety of anilides (I) and (VII) with acetic acid (II) or alcohols (V) in the system PIFA—BF3·OEt2 provides access towards the corre-sponding acetoxylation or alkoxylation products. The reaction proceeds with excellent regioselectivity in para-position to the amide group. The free alcohol (IV) is obtained in the presence of formic acid or bulky tert-butyl alcohol. — (LIU, H.; WANG, X.; GU*, Y.; Org. Biomol.
