Palladium catalyzed carbonylationAcylpalladium complexesCarbomethoxypalladium complexesIn the palladium catalyzed alkoxycarbonylation of cinnamyl chloride two mechanisms play a role. An associative mechanism was observed at low pressure, while an insertion mechanism was observed at high pressure or when an ...

Small, strained rings have rigid, defined conformations and unique electronic properties. For these reasons, many groups seek to use these subunits to form biologically active molecules. We report a generally applicable approach to attach small rings to
A plausible mechanism, which features distinctive Pd-II-mediated decarbonylative coupling and unprecedented nucleophilic attack of carboxylates to Pd-II-ligated isocyanides, was proposed to account for this reaction.关键词: Amides Carboxylic acids Palladium Decarbonylation Isocyanides ...
