摘要:Preparation of aminodiphenylamines involves reacting nitrohalobenzenes withanilines in the presence of a base and a catalyst (I), then hydrogenation of the resultantintermediate nitrodiphenylamines in the usual way, where (I) is a copper complex of anoptionally bridged or oligomeric organic phosphine, phosphonite or phosphite orcorresponding amino or thio substituted compound. Preparation of
aminodiphenylamines involves reacting nitrohalobenzenes with anilines in the presence ofa base and a catalyst of formula (I), then hydrogenation of the resultant intermediatenitrodiphenylamines in the usual way: X = O, NH, S or CnH2n; n = 0, 1, 2 or 3; M = 6-18 Caryl, 1-19 C alkyl, 7-19 C aralkyl or 6-9 C heteroaryl with 1-3 heteroatoms, where 2 ormore M groups may be linked by a covalent bridge or a 1-4 C alkylidene bridge; Y =halogen, trifluoroacetyl, trifluoromethanesulfonyl, nonafluorobutanesulfonyl, CN, acetyl,optionally fluorinated acetylacetonyl, nitrate, arylsulfonyl, oxinate, phosphate, carbonateor tetrafluoroborate group; z = 1, 2 or 3; m = 1-6; r = 0, 1 or 2; s = 0 or 1. An Independentclaim is also included for preparation of nitrodiphenylamines by reactingnitrohalobenzenes with aniline in the presence of a base and a complex (I).
