| abstract | 1,202,166. Phenoxyphthalic acid esters. FARBENFABRIKEN BAYER A.G. 13 June, 1968 [26 July, 1967], No. 28091/68. Heading C2C. [Also in Division A5] Invention relates to phenoxyphthalic acid esters of the general formula in which R<SP>1</SP> is an electrophilic radical and R 2 and R<SP>3</SP> which may be the same or different denote aliphatic or aromatic hydrocarbon radicals. R<SP>1</SP> may be NO 2 , CN, COOR<SP>4</SP>, SO 2 R<SP>4</SP> or COR<SP>4</SP> group and R<SP>4</SP> may be alkyl or phenyl group. The compounds may be prepared by reacting an alkali metal salt or an alkaline earth metal salt of a hydroxyphthalic acid ester in a polar organic solvent at a temperature in the range of from 50‹ to 200‹ C. with a halogenated benzene derivative which is substituted by at least one electrophilic group. In an example 4-hydroxy phthalic acid was reacted with p-chloro nitro benzene to produce dimethyl ester of 4-(4<SP>1</SP>-nitrophenoxy) phthalic acid. |
