Reaction Steps
Example 1 was repeated with 14.1 g of a powdered titanium diboride from H. C. Starck at 140° C. After 2 hours' reaction time, phenol conversion was 27.7%, wherein 0.06 g of phenyl chloroformate and 43.9 g of diphenyl carbonate were formed. Selectivity for carbonates was approximately 99%.
