Reaction Conditions:
with dihydrogen peroxide;sodium hydroxide in tetrahydrofuran;methanol; pH=10 at 70; for 4 h;
Steps:
General Procedure for C-C Cleavage of Oxidized Lignin Model Compound by Hydrogen Peroxide in Aqueous Alkaline Media:
4 mL of hydrogen peroxide 30% adjusted pH at 10.0 by NaOH was added to 3 (0.5 mmol, 165.0 mg). This suspension was heated at 70° C. for 4 h. After that, the reaction mixture cooled down and the reaction mixture was acidified by aqueous HCl (0.5 M) solution (pH 3.0). Organic compounds were extracted by ethyl acetate (3×30 mL). Organic layers combined, dried over MgSO4, filtered and concentrated under vacuum. The residue was submitted to NMR spectroscopy and yield of any individual compound determined by internal standard (mesitylene).
