Kavala, Veerababurao published the artcileSyntheses and regiochemistry of enol addition to 9-phenyl-9H-xanthen-9-ol, COA of Formula: C19H14O2, the publication is Tetrahedron (2008), 64(18), 3960-3965, database is CAplus.
Regioselective C-C bond formation of 9-phenyl-9H-xanthen-9-ol 1 with various enolizable ketones I-X in an acidic (HBr) medium, obtained by the reaction of 1,1′-(ethane-1,2-diyl)dipyridinium bistribromide (EDPBT) with ketone is observed Except for ketone, 4-methyl-pentan-2-one VII in all other cases examined the attack to xanthenyl carbocation is from the thermodynamically stable enolizable side of the unsym. ketones. In the case of 3-methyl-butan-2-one VIII the equilibrium is in favor of the more stable enolizable ketone, which has large steric factor, hence no reaction was observed during its addition to alc. 1.
