| titleOfInvention | Process for the preparation of asymmetrically substituted biaryldiphosphines |
| abstract | A process for the preparation of asymmetrically substituted biaryldiphosphine ligands of the following formula (I) from 2,2 ′, 6,6′-tetrabromobiphenyl by bromine-metal exchange and subsequent reaction is provided: [Chemical 1] Wherein R 1 is C 1-6 -alkyl or C 3-10 -cycloalkyl optionally substituted with one or more halogen atoms, R 2 and R 3 are the same and are C 5-10 -cycloalkyl or C 1-6 -alkyl, Or, R 2 is C 5-10 -cycloalkyl or C 1-6 -alkyl, and R 3 is a halogen atom, nitro, amino, C 1-6 -alkyl, C 1-6 -alkoxy, and di- Aryl optionally substituted with one or more substituents selected from the group consisting of C 1-6 -alkylamino groups; And each of C 1-6 -alkyl, C 1-6 -alkoxy, di-C 1-6 -alkylamino, and C 5-10 -cycloalkyl in R 2 and R 3 is one or more halogen atoms. Optionally substituted. [Selection figure] None |
