Electrosynthesis as a Powerful Method for the Generation of Catalytic Intermediates: Efficient Isolation of a Palladium Aryl Halide Oxidative Addition Product

Polyphosphane ligands of controlled conformation promote highly efficient palladium-catalyzed cross-coupling reactions. Electrosynthesis has been used as a new straightforward method to obtain important intermediates in the search for a better mechanistic understanding. As a proof of concept, the facile synthesis of a phenyl iodopalladium(II) complex (2) was conducted at the electrolysis scale from a readily electrogenerated unstable Pd0 precursor (see scheme).
