Notes:
The reaction of nitrosubstituted aryl fluorides 1 with cyclic β-diketones 2 proceeds at 20-80°C in the presence of bases, such as KOH, KF or NaOEt, leading to the aryl ethers 3a-m. Depending on the base the reaction of dimedone 2a or 1,3-cyclohexanedione 2b with 2,4-dinitrofluorobenzene 1a or 4-fluoro-3-nitrobenzonitrile 1b furnishes C- and/or O-arylated products. Upon heating of 3g, e and 3m at 40-100°C in DMF/K2CO3, the C-arylated ketones 4a-c are formed in good yields. Starting from 3a we obtained the chromenedione 5 under the same conditions.
