Carbonylation of Organomercury Compounds: A General Synthesis of Carboxylic Acids and Esters

Organomercury compounds react with carbon monoxide in aqueous or alcoholic media to give good yields of carboxylic acids or esters.The carboxyl group is introduced selectively at the site of the carbon-mercury bond.Homogeneous group 9 and 10 metal complexes catalyze this carbonylation reaction, which yields mercury(0) as the inorganic byproduct.The mercuration-carbonylation sequence represents a general synthesis of carboxylic acids and esters.

Anion-Binding Catalysis by Electron-Deficient Pyridinium Cations

A new activation principle in organocatalysis is presented: halide binding through Coulombic interactions. This mode of catalysis was realized by using 3,5-di(carbomethoxy)pyridinium ions that carry an additional electron-withdrawing substituent on the nitrogen atom, for example, pentafluorobenzyl or cyanomethyl. For the N-pentafluorobenzyl derivative, Coulombic interaction with the pyridinium moiety is complemented in the solid state by anion-π interactions with the perfluorophenyl ring. Bromide and chloride are bound by these cations in a 1:1 stoichiometry. Catalysis of the C-C coupling between 1-chloroisochroman (and related electrophiles) with silyl ketene acetals occurs at -78 °C and at low catalyst loading (2 mol %).

Reaction of acetals with various carbon nucleophiles under non-acidic conditions: C-C bond formation via a pyridinium-type salt

Mild substitution reactions of acetals with carbon nucleophiles via the pyridinium-type salts generated by the treatment of acetals with TESOTf-2,4,6-collidine or 2,2′-bipyridyl have been developed. Various carbon nucleophiles, such as organocuprates, sil

Dicationic palladium(II)-spiro bis(isoxazoline) complex for highly enantioselective isotactic copolymerization of CO with styrene derivatives

The enantioseletive alternating copolymerization of CO with styrene derivatives catalyzed by a dicationic palladium(II) complex of tetra isopropyl-substituted spiro bis(isoxazoline) (i-Pr-SPRIX) is developed. This polymerization proceeded efficiently to p

Process for the preparation of cinnamic acid esters

A process for the preparation of a cinnamic acid ester comprises condensing a benzaldehyde with an acetic acid ester in the presence of a base. The reaction mixture is then treated, without adding an additional solvent or after adding an additional solvent, with an acid to convert a 3-alkoxy-3-phenylpropionic acid ester in the reaction mixture into a corresponding cinnamic acid ester. This procedure allows cinnamic acid ester derivatives of high-purity to be obtained in good yield.

Anodic Oxidation of 1-Aryl-2,2-dihalogenocyclopropanes in Methanol or Acetonitrile Media

3-Aryl-1,1-dichloro-3-methoxypropenes, methyl 3-aryl-3-methoxypropionates and 3-acetamido-3-aryl-1,1-dichloropropenes were obtained along with N-acetyl-4-aryllactams via anodic oxidation of 1-aryl-2,2-dichlorocyclopropanes in methanol and acetonitrile solutions, respectively.
