The reaction of benzil with phenol at 180degreesC in the presence of SnCl4.5H(2)O produces a benzofuran, a benzofuranol, a benzodifuran, and a benzofuranone. Anhydrous tin(IV) chloride also gives a benzofuranofuranone. Other phenols and their methyl ethers yield related products. The good yields of the benzo- and naphtho-furanones make the method an attractive alternative to the benzilic acid route to such compounds. (C) 2002 Elsevier Science Ltd. All rights reserved.
