Abstract

The valorization of alkanes is possible via carbon-carbon coupling reactions. A series of dialkyl cobalt complexes [(RCH2)2CoIII(bpy)2]ClO4 (R = H, Me, Et, and Ph) were reacted with the H5PV2Mo10O40 polyoxometalate as a catalyst, leading to a selective oxidative carbon-carbon bond coupling reaction. The reaction is initiated by electron transfer from [(RCH2)2CoIII(bpy)2]+ to H5PVV2Mo10O40 to yield an intermediate [(RCH2)2CoIV(bpy)2]2+-H5PVIVVVMo10O40, as identified by a combination of EPR and X-ray photoelectron spectroscopy experiments. The reaction is catalytic with O2 as terminal oxidant representing an aerobic C-C bond coupling reaction.
