4-Anisyl phenyl ketone

The migration aptitudes in the reaction of ketones with peracetic acid in acetic acid as a solvent are in the order -anisyl > phenyl > >-nitro-phenyl.82 Cyclohexyl and phenyl are about equal in migration aptitude... 

Phenyl trifluoroacetate (149) undergoes oxidative addition to generate the acyl-palladium 150 [64], Based on this reaction, trifluoromethyl ketones such as 151 can be prepared by Suzuki coupling with arylboronic acids. Similarly, anisyl heptafluoropropyl ketone (154) was prepared by the Suzuki coupling of phenyl heptafluorobutyrate (152) with anisylboronic acid 153 [65]. 

The dehydrogenative condensation of unsaturated ketones with methyl ketones was used for preparing various series of 2,4,6-tri-arylpyrylium salts not only by Dilthey, but also by Wizinger and co-workers (for combinations of phenyl, p-anisyl, and p-dimethyl-aminophenyl substituents), by Amoros-Marin and Carlin (combinations of phenyl and p-chlorophenyl), by Le Fevre and Le Fevre (for combinations of pbenyl and m- or p-nitrophenyl), and by others. ... 

Hypervalent iodonium salts (RI+PhX ) selectively transfer the R group (phenyl, p-anisyl, 2-thienyl, ( )-/3-styryl) and couple with R of R SnBus to furnish unsymmetri-cal ketones in excellent yields under very mild reaction conditions within a short period of time (1 atom of CO, 0.2% of PdCl2, 25 °C, 20 min) (Scheme 11). The reaction is most successfully performed in an aqueous medium (DME/H2O, 4 1). In dry DME, the reaction does not give clean products.
