On the performance of Au(111) for ethylene epoxidation: a density functional study
This study reveals that ethylene epoxidation on gold surfaces is possible with adsorbed atomic oxygen. Calculations show gold surfaces achieve approximately 40% selectivity for epoxide formation, matching experimental results.
Area of Science:
- Surface Science
- Catalysis
- Computational Chemistry
Background:
- Investigates the epoxidation mechanism of ethylene on a gold(111) surface using periodic density functional theory.
- Examines the role of adsorbed atomic oxygen in enabling partial oxidation reactions.
Discussion:

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...

Acidity of 1-Alkynes
The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.
