  Decarbopalladation of π-Allylpalladium Intermediates Formed from Palladium-Catalyzed Arylations of 3-Allen-1-ols

  摘要：

  Unusual palladium-catalyzed arylative fragments of acyclic 3-alien-1-ols were observed. Oxidative addition of Pd(0) to aryl halides would form the arylpalladium halides, which added to the central carbon of allenes via carbopalladation to form the pi-allylpalladium intermediates. The pi-allylpalladium intermediates would be reductively eliminated via carbon-carbon cleavage to give the arylated dienes and the alpha-hydroxyalkylpalladium intermediates, which were further reductively eliminated to the corresponding aldehydes.
