Abstract

1325792 Chlorocarbonic esters BAYER AG 19 April 1971 [28 Feb 1970] 22652/71 Heading C2C [Also in Division C3] Chlorocarbonic acid ester-carboxylic acid chlorides of the formula in which Hal is chlorine and R<SP>1</SP> is a divalent aromatic radical arc prepared by reacting the appropriate hydroxycarboxylic acid in a solvent in the presence of an organic tertiary base with phosgene. The Examples describe the reaction of m- and p-hydroxybenzoic acid with phosgene to give the corresponding chlorocarbonic acid ester-acid chlorides.
