(PCP)Ir (PCP = κ3-C6H3-2,6-[CH2P(t-Bu)2]2) is found to undergo oxidative addition of the methyl−oxygen bond of electron-poor methyl aryl ethers, including methoxy-3,5-bis(trifluoromethyl)benzene and methoxypentafluorobenzene, to give the corresponding aryloxide complexes (PCP)Ir(CH3...

Through tuning both composition and pores, the 3D Nヾoped nanocarbon with a high ratio of sp3/sp2 on the surface exhibits a superior electrocatalytic performance for ORR than that of the commercial Pt/C in the Zn゛ir battery. The density functional theory calculation results suggest that the...
C-H bond activation has been extensively studied with (Cp*)M(L)n (M = Ir, Rh), but cobalt, the third member of this triad, has not previously been shown to activate sp3 C-H bonds. Further, practical functionalization of the metal alkyl products of oxidative addition has not been fully...

Carbon–carbon (C–C) bond formation is a cornerstone of synthetic chemistry, relying on routes such as transition-metal mediated cross-coupling for the introduction of new carbon-based functionality. For {[M]n +–C} (M = metal) structural units, studies that offer well-defined relationships ...
