m-C6H4(COCl)2 (144 g.) and 5 g. Fe, treated at 95-100° with Cl until there is no further increase in weight, give 137 g. 5-Cl derivative (I), b4 126-8°; 16 g. I and 100 cc. 10% NaOH, warmed 5 hrs. on a steam bath, give 11 g. 5,1,3-ClC6H3(CO2H)2. I (5 g.) and 50 cc. MeOH, heated 0.5 hr. on the steam bath, give 5,1,3-ClC6H3(CO2Me)2, m. 80-1°. I (10 g.) and 100 cc. NH4OH give 8 g. 5-chloroisophthalamide, m. 254-5°. p-C5H4(COCl)2 (215 g.) and 5 g. Fe at 175°, treated with Cl until there is no further increase in weight, give 223 g. 2,3,5,6-tetrachloroterephthaloyl chloride (II), m. 144-5°; 10 g. II and 300 cc. MeOH, refluxed 10 hrs., give 9.3 g. di-Me 2,3,5,6-tetrachloroterephthalate, m. 154-5°; the free acid m. about 330° (decomposition); the amide m. above 400°.
