| titleOfInvention | METHOD FOR PRODUCING AROMATIC AMINES IN THE PRESENCE OF A PALLADIUM COMPLEX INCLUDING FERROCENILBIPHOSPHIN LIGAND |
| abstract | 1. A method of obtaining compounds of formula I! ! where the group R1 is 1,3-dimethylbutyl, 1,3,3-trimethylbutyl or the group A1! ! where the groups R3, R4 and R5 each independently of one another are hydrogen or C1-C4 alkyl and! the group R2 is hydrogen; or ! R1 and R2 together form the group A2! ! where the groups R6 and R7 each independently of one another are hydrogen or C1-C4 alkyl; or ! R1 and R2 together form a group A3! ! where the groups R8 and R9 each independently of one another are hydrogen or C1-C4 alkyl; ! in which the compound of formula II! ! where the groups R1 and R2 are defined as indicated for formula I, and X is bromo or chloro, is reacted with ammonia in the presence of a base and a catalytic amount of at least one palladium complex, where the palladium complex includes at least one ferrocenyl bisphosphine ligand. ! 2. The method according to claim 1, where R1 is a group A1, where R3, R4 and R5 are each independently hydrogen or C1-C4 alkyl; and R2 is hydrogen; or R1 and R2 together form a group A2, where R6 and R7 are each independently hydrogen or C1-C4 alkyl; or R1 and R2 together form a group A3, where R8 and R9 are each independently hydrogen or C1-C4 alkyl. ! 3. The method of claim 1, wherein the palladium complex compound comprises at least one ligand selected from R (-) - di-tert-butyl [1 - [(S) -2- (dicyclohexylphosphinyl) ferrocenyl] ethyl] -phosphine and racemic di-tert-butyl [1- [2- (dicyclohexylphosphinyl) ferrocenyl] ethyl] phosphine. ! 4. The method of claim 1, wherein the palladium complex compound comprises racemic di-tert-butyl- [1- [2- (dicyclohexylphosphinyl) ferrocenyl] ethyl] phosphine. ! 5. The method according to p. 1, where |
