Reaktionsschritte
Example 1 was repeated with 14.1 g of a powdered tungsten monoboride from Strem at 140° C. After 2 hours' reaction time, phenol conversion was 17.3%, wherein 4.8 g of phenyl chloroformate and 24.2 g of diphenyl carbonate were formed. Selectivity for carbonates was approximately 99%.
