| titleOfInvention | Production of 1-n,n-diphenylaminopyrene derivative |
| abstract | PURPOSE: To readily obtain a 1-N,N-diphenylaminopyrene derivative useful as an electrophotographic organic photoconductive material by reacting a 1- halogenopyrene used as a raw material with a diphenylamine derivative. n CONSTITUTION: A 1-halogenopyrene (e.g. 1-iodopyrene) expressed by formula I (X is halogen) is reacted with a diphenylamine derivative (e.g. 4,4'- dimethyldiphenylamine) expressed by formula II (R 1 and R 2 are H, halogen, cyano-substituted or unsubstituted alkyl, alkoxy or phenyl), preferably in the presence of copper powder, copper oxide or a copper halide in or without a solvent in an atmosphere of nitrogen by adding an alkaline salt in an amount sufficient to neutralize hydrogen halides formed as a by-product in the condensing reaction. Thereby, a 1-N,N-diphenylaminopyrene derivative [e.g. 1-N,N-bis (4-methylphenyl)aminopyrene] expressed by formula III is obtained. The resultant compound is useful also as a charge transport substance in function separating type photosensitive units. n COPYRIGHT: (C)1992,JPO&Japio |
