Bis (aminostyryl) benzene compounds and synthetic intemediates thereof, and process for preparing the compounds and intermediates |
摘要 |
A bis(aminostyryl)benzene compound of the following general formula [I] is provided wherein R2 and R3 independently represent an unsubstituted aryl group, and R1 and R4 independently represent an aryl group, and R5 to R8 independently represent a cyano group or the like. A process for the preparation thereof is described wherein a 4-(N,N-diarylamino)benzaldehyde and a diphosphonic acid ester or diphosphonium salt are, for example, subjected to condensation reaction. Intermediates of the bis(aminostyryl)benzene compound are also described.
