资源简介：
The reactivity of
(PNP)Rh(Ph) (PNP = 2,6-bis(dialkylphosphinomethyl)pyridine)
toward a variety of electrophiles (Ar–I, ArCH2Cl,
O2, I2, B2pin2, and ArSO3H) was explored, and several new modes of oxidative reactivity
were observed. Substituting tBu2P for iPr2P provided 100-fold
rate enhancement toward C–H bond activation and addressed the
previously reported challenge of N2 inhibition. Studying
the stoichiometric reactivity of (PNP)Rh complexes toward C–H
cleavage and oxidative functionalization led to (PNP)Rh-catalyzed
cross-coupling of aryl iodides with sp2 and sp3 C–H bonds.
