Pd(II)-catalyzed enantioselective C-H activation of phenylacetic acids followed by an intramolecular C-O bond formation afforded chiral benzofuranones. This reaction provides the first example of enantioselecctive C-H functionalizations through Pd(II)/Pd(IV) redox catalysis.

Highly dispersed potassium on alumina (K/Al2O3) acts as a metalating agent towards enolizable compounds and the intermediate organopotassium derivatives can be alkylated with primary alkyl bromides.The reaction conditions are dependent on the substrate.In particular, tetrahydrofuran is the solvent of choice for the metalation of nitriles and aldehyde N,N-dimethylhydrazones at -60 deg C and of N-cyclohexyl ketimines at room temperature, whereas hexane must be used for ketones.
