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.
