Alteration of Reaction Course in Thermolysis of <i>cis</i>-Diethylbis(tertiary phosphine)palladium(II) from Reductive Elimination to β-Elimination Process Induced by Addition of Tertiary Phosphine Ligand

Abstract

Abstract Addition of tertiary phosphine to a solution containing cis-diethylbis(tertiary phosphine)palladium(II) alters thermolysis course of the complex from reductive elimination process liberating butane to β-hydrogen elimination process in which ethane and ethylene are released. Study with a deuterium-labeled ethyl complex indicates involvement of an internal metalation process.
