Unexpected isolation, and structural characterization, of a -hydrogen-containing -alkylpalladium halide complex in the course of an intramolecular Heck reaction. Synthesis of polycyclic isoquinoline derivatives

The isolation of a stable -hydrogen-containing R-PdLn-X complex (R = alkyl; X = halide) issued from a Heck reaction is reported together with some aspects of its reactivity.
