2,3-Diphenyl-, 2-phenyl-3-methyl-, and 2-methyl-3-phenyl(F-benzo)furans were oxidized with chromium trioxide in acetic acid to yield 2-benzoyl-F-phenyl benzoate, 2-acetyl-F-phenyl benzoate, and 2-benzoyl-F-phenyl acetate respectively, while 2-phenyl(F-benzo)furan was least susceptible to the same reagent, affording 1-(2-hydroxy-F-phenyl)-2-phenylethanedione in a poor yield. The spectral data of the products were compatible with the structure of ortho-disubstituted F-benzene.
2,3-Diphenyl-, 2-phenyl-3-methyl-, and 2-methyl-3-phenyl(F-benzo)furans were oxidated with chromium trioxide in acetic acid to produce 2-benzoyl-F-phenyl benzoate, 2-acetyl-F-phenyl benzoate、而 2-苯基(F-
苯并呋喃)最不容易受到相同试剂的影响,生成的 1-(2-羟基-F-苯基)-2-苯基乙二酮收率很低。产物的光谱数据与正交二取代 F-苯的结构相符。
