Oxidative coupling of alcohols on gold: Insights from experiments and theory

Author affiliations

Abstract

Molecular level understanding of the mechanism of oxidative coupling of alcohols on metallic Au(111) activated by oxygen is achieved through a combination of experiments and theoretical calculations. The facility of the β–H elimination of the alkoxys, which increases with the length of the alkyl chain, is identified to be critical in determining the product distributions. Dioxymethylene serves as a formaldehyde reservoir in the cross-coupling reaction between methanol and formaldehyde through its reversible formation and decomposition, contributing to the high selectivity for the coupling products.
