3,3-Bis[1,1-bis(4-disubstituted aminophenyl)ethylen-2-yl]- 4,5,6,7-tetrachlorophthalides (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).
