Copper-Catalyzed Oxidative Cleavage of the C–C Bonds of β-Alkoxy Alcohols and β-1 Compounds
[Image: see text] Copper-catalyzed aerobic oxidation conditions were employed to promote the C–C bond cleavage of β-alkoxy alcohols and β-1 compounds (lignin model compounds). Besides these compounds, various 1,2 and 1,3-diols were successfully converted to aldehydes. We propose the Cu(I)-catalyzed...

Sumario: | [Image: see text] Copper-catalyzed aerobic oxidation conditions were employed to promote the C–C bond cleavage of β-alkoxy alcohols and β-1 compounds (lignin model compounds). Besides these compounds, various 1,2 and 1,3-diols were successfully converted to aldehydes. We propose the Cu(I)-catalyzed mechanism explaining the C–C cleavage of these 1,2 and 1,3-dihydroxy compounds and β-alkoxy alcohols based on XPS data. Although our reaction conditions do not include large excess of bases and elaborated ligand-modified catalysts, copper salts with/without Me-TBD show good catalytic activities for C–C bond cleavage of various lignin model compounds. |
