| abstract | NEW MATERIAL:A compound of formula I (R 1 is lower alkyl or phenyl; R 2 and R 3 are lower alkyl, benzyl or phenyl). n EXAMPLE: 4-Methoxy-4'-N,N-diphenylaminostilbene. n USE: Useful as an organic photoconductive material for electrophotography, optical whitening agent and electron charge transfer substance in functional separating photosensitive materials, and capable of removing disadvantages of the photoconductive materials in the photosensitive materials. n PROCESS: A phenyl derivative of formula II [Y is triphenylphosphonium of formula III (Z - is halogen ion), etc.] is reacted with an aldehyde compound of formula IV in the presence of a basic catalyst, e.g. caustic soda, at room temperature W about 100°C to give the compound of formula I . Dimethyl sulfoxide (DMSO), N,N-dimethylformamide, etc. are preferred for a reaction solvent. n COPYRIGHT: (C)1984,JPO&Japio |
