Reaction Steps
Example 1 was repeated at 140° C. with 14.1 g of a powdered hafnium dioxide from the Aldrich company. After 2 h reaction time, the phenol conversion was 3.7%, whereby 3.5 g phenyl chloroformate and 3.3 g diphenyl carbonate were formed. The selectivity to carbonate esters was ca. 97%.
