Phenyl chloroformate is a chemical compound that serves as an intermediate in the production of various carbonic acid derivatives.

Chemical properties

Phenyl chloroformate belongs to the group of chloroformic acid esters , as well as ethyl chloroformate , methyl chloroformate , isopropyl chloroformate , n- butyl chloroformate and benzyl chloroformate .

use

Phenyl chloroformate is used as an intermediate in the production of the pesticides amidosulfuron , buprofezin , flazasulfuron , imazosulfuron , nicosulfuron , prosulfuron , pyrazosulfuron , rimsulfuron and thidiazuron as well as for further syntheses.

nomenclature

The common name "phenyl chloroformate" is incorrect, as it is a derivative of carbonic acid , not a derivative of formic acid . It is the monochloride and at the same time the monophenyl ester of carbonic acid.
