Chemoselective synthesis of diphenyl-benzolactones under montmorillonite K-10 catalysis
Sharifi, Ali,Abaee, M. Saeed,Mirzaei, Mojtaba
experimental part, p. 319 - 322 (2010/07/10)
Montmorillonite K-10 supported condensation of benzil with phenols is investigated. Selective synthesis of the corresponding benzofiiranone products is observed in good yields.
Condensations of benzil with phenols and aryl ethers mediated by tin(IV) chloride pentahydrate

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 compounds.
Anodic oxidation of 2,3-diarylbenzofurans : Different reaction pathways for the cation radical
Cariou, Michel,Simonet, Jacques
, p. 4913 - 4916 (2007/10/02)
The electrooxidation of 2,3-diarylbenzofurans leads to a rearrangement lactone, 3,3-diaryl-2(3H)-benzofuranone, together with a ring enlargement product, 9-aroyl-9-hydroxy-(9H)-xanthene. However, in some cases coupling products may be isolated in high yie
