Summary[edit]
| Description |
Deutsch: Katalysezyklus der Negishi-Kupplung.
Das Ziel der Umsetzung ist die kovalente Verknüpfung des (aromatischen) Molekülfragments Ar mit dem Molekülfragment R. Dabei kann statt Nickel auch Palladium verwendet werden. L bezeichnet die Liganden des Metallions. Bei der Abgangsgruppe X handelt es sich häufig um ein Halogenid.
English: Catalytic cycle of the Negishi coupling.
The reaction results in a covalent bond between (aromatic) molecule fragment "Ar" and molecule fragment "R". For catalysis, Pd may also be used in place of Ni. "L" denotes the ligands of the catalyst metal ion. The leaving group "X" usually is a halide. |
