Catalytic tandem oxy-palladation and vinylation

Article abstract of DOI:10.1016/S0040-4039(00)79288-4

Intramolecular oxy-palladation of hydroxy-alkenes leads to organo-Pd(II) intermediates which can be trapped by alkenes in chain extension by vinyl substitution; catalysis is efficient using a reoxidation system but the process is limited to substrates which cannot undergo β-hydride elimination from the organo-Pd(II) intermediate.
