An efficientpalladium-catalyzed oxidative amination of olefins with secondary anilines for the synthesis of tertiary (E)-enamines has been developed. Trimethylacetic acid (PivOH) played an important role in the reaction. This protocol tolerates a range of functional groups and is a reliable method for direct synthesis of tertiary (E)-enamines in high yields undermildconditions.

The t-Bu-P4 base was found to be an excellent catalyst for the condensation of trimethylsilylacetate or trimethylacetonitrile with carbonylcompounds to form functionalized alkenes and beta-enaminoesters were also synthesized by the condensation with formanilides.
