HCID 7597Diphenyl carbonate

Procedure

Example 1 was repeated at 160° C. After 2 h reaction time, the phenol conversion was 11.9%, wherein 0.6 g of phenyl chloroformate and 18.6 g of diphenyl carbonate were formed. The selectivity to give the carbonate and phenyl chloroformate was greater than 99%.
