Product 1

HCID 7597Diphenyl carbonate

Procedure

Example 1 was repeated with 14.1 g of a powdered ditungsten boride from Strem at 140° C. After 2 hours' reaction time, phenol conversion was 8.8%, wherein 4.7 g of phenyl chloroformate and 10.7 g of diphenyl carbonate were formed. Selectivity for carbonates was approximately 98%.
