Outline of Final Research Achievements	The coordination behavior of heteroarenes to a palladium center has attracted much attention since their coordination has been thought to be involved in Pd-catalyzed transformations of heteroarenes. While the eta1-sigma-coordinating heteroarenes complexes have been proposed in the Pd-catalyzed processes, the coordination behavior of heteroarenes has been still elusive. We demonstrated that there is a sigma-pi continuum for eta1-indole-Pd complexes through successful isolation, systematic structure analysis and theoretical calculation analysis of a series of non-anchored indole-Pd(II) complexes.
