| Abstract: | 3,3- Bis [ 1,1 - bis (4 - disubstituted aminophenyl) ethylen - 2 - yl ] - 4,5,6,7- te-trachlorophthalides(4) were synthesized by the condensation of tetrachlorophthalic anhydride with 1,1- bis(4 - disubstituted aminophenyl)ethylenes(3) in acetic anhydride in the presence of p - toluene-sulfonic acid, yields 89% - 93 % . Compound 3 were prepared by the dehydration of 1,1 - bis(4 - disubstituted aminophenyl)ethanols(2) which were synthesized by Grignard reaction of 4,4' - bis(N,N- disubstituted amino) benzophenones (1) with methyl magnesium iodide, yields 85 % -88.5 % (based on 1). |
