N, N, N' and N' {4,4 ' and 4 ' ', 4' '' - tetrakis (N, N diaryl amino) phenyl} 1,4 phenylenediamine and its production mannered

摘要

PROBLEM TO BE SOLVED: To obtain the subject new compound as a new starburst-type amine with high heat resistance and low ionization potential. ;SOLUTION: This new compound is a compound of formula I (R is H or an alkyl), e.g. N,N,N',N'-[4,4',4",4'''-tetrakis(N,N-diphenylamino)phenyl]-1,4- diaminobenzene. The compound of formula I (for example, when R is H or a 3-methyl group) is obtained by reaction of N,N,N',N'-(4,4',4",4'''- tetrakisaminophenyl)-1,4-diaminobenzene with a cyclohexanone compound of formula III (e.g. cyclohexanone, methylcyclohexanone) in the presence of a hydrogen-transfer catalyst.;COPYRIGHT: (C)2000,JPO
