The reaction between diethyl(α‐acetoxymethyl)vinylphosphonate 1 and nitrogen‐ or sulfur‐based nucleophiles occurs easily at room temperature in water as a solvent in the presence of 1,4‐diazabicyclo [2.2.1]octane (DABCO) as an organocatalyst. This simple procedure enables the synthesis of nitrogen‐ and sulfur substituted vinylphosphonates, and also allows a convenient use of water‐soluble salts as...
The palladium catalyzed hydroesterification of 1-octene with isosorbide was studied in standard and Brønsted acidic ionic liquids as reaction media. High conversions and selectivities towards the targeted isosorbide diesters have been achieved by using a catalytic system composed of Pd(OAc)2 and trisulfonated triphenylphosphine dissolved in 1-(4-sulfonic acid)-butyl-3-methylimidazolium tosylate. The...
