The reaction of benzil with phenol at 180°C in the presence of SnCl4·5H2O 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

in 2002, Musgrave et al questioned Liebig's acid-catalyzed rearrangement mechanism for this polycyclic formation reaction (2). Their reinvestigation into the condensation of benzil with phenol under various conditions, including the use of hydrated and anhydrous SnCL», shed light on the structure of the products and the mechanism of the reaction, indicating the formation of several compounds with 1 and
