Palladium-catalyzed coupling of aryl iodides, nonconjugated dienes and carbon nucleophiles by palladium migration
摘要:
Aryl iodides, nonconjugated dienes, and carbon nucleophiles react in the presence of a palladium catalyst to give good yields of coupled products apparently formed by arylpalladium generation and addition to the less substituted end of the diene, palladium migration down the carbon chain to form a pi-allylpalladium intermediate, and carbanion displacement of the palladium moiety.
