Intramolecular, reversible C–H oxidative addition–reductive elimination at rhodium. Reaction of the intermediate with different types of C–H bonds and dihydrogen

Abstract

The ortho-metallated complex [{(Ph₂PCH₂CH₂)₂N(CH₂CH₂PPhC₆H₄)}RhH](SO₃CF₃) thermally or chemically undergoes reductive elimination of the substituted phenyl group; the N(CH₂CH₂PPh₂)₃Rh⁺ fragment thus formed is stabilized by CO, halides, C₂H₄, or engaged in oxidative additions of H₂ and C–H bonds from arenes, alkynes, and aldehydes.
