conditions was obtained from observation of the protonolysis at low temperature. During the course of all catalytic reactions, the resting state of the catalyst was palladium alkyl complex 7, indicating that protonolysis of the Pd-C bond was the turnover-limiting step. Kinetic studies reveal an unusual inverse dependence of the reaction rate on the concentration of the aminoalkene substrate. This effect can

A mild and facile Pd-catalyzed intramolecular hydroamination of unactivated alkenes is described. This reaction takes place at roomtemperature and is tolerant of synthetically useful acid-sensitive functional groups. The formation of hydroamination products rather than oxidative amination products is due to the use of a tridentate ligand on Pd which effectively inhibits beta-hydride elimination.
