Abstract treatment of the title compounds with acyl halide and Lewis acid affords unsaturatedketones (mainly α-β with aluminium chloride, selectively β-γ with silver tetrafluoroborate). Reduction of the alkenyl group gives polyfunctional ketones.

Abstract A convenient synthetic method for the preparation of symmetric acyclic diketones from dicarboxylic acids is provided. Three bis‐benzimidazolium salts were used as tetrahydrofolatecoenzymemodel, thus the biomimetic synthesis of three symmetric acyclic diketones was successfully accomplished by using the addition‐hydrolysis reaction of corresponding bis‐benzimidazolium salts with methyl magnesium

The acidcatalysed condensation of diketones with pyrrole did not result in the formation of expected divergent bisdipyrromethane always; instead the product depends on the chain length of the diketones, in particular the distance between the two carbonyl functional groups. When the two carbonyl groups are linked via one or two methylene groups, unusual ring annulation occurs resulting in the formation
