Procedure

Example 1 was repeated with 14.1 g of a powdered zirconium diboride from H. C. Starck at 140° C. After 2 hours' reaction time, phenol conversion was 35.7%, wherein 0.4 g of phenyl chloroformate and 54.9 g of diphenyl carbonate were formed. Selectivity for carbonates was greater than 96%.
