Abstract
The reactive HO˙/(Salophent-Bu)Co(II) radical pair was observed to be generated via homolysis of the terminal Co(III)-OH bond in transient (Salophent-Bu)(L)Co(III)(OH) (L = Py, MeOH) complexes as indicated by UV-Vis and EPR measurements. Based on this elementary process, C-H bond activations in acetone, 2-butanone, acetonitrile and benzene were achieved under ambient conditions. For the reactions of the first three substrates, the alkylcobalt(III) complexes were formed as the products.

Abstract
A new family of rhodium porphyrin complexes bearing a primary, secondary or benzylic perfluoroalkyl ligand RhIII(btpp)RF [btpp = 5,10,15,20-tetrakis(4-tert-butylphenyl)porphyrinato dianion] has been successfully synthesized in good yields using commercially available perfluoroalkyl iodides RFI (RF = nC3F7, iC3F7, nC4F9, nC6F13, cC6F11, nC10F21 and C6F5CF2) and the air-stable precursor RhIII(btpp)Cl under basic conditions. Mechanistic investigations suggest a halogen atom transfer pathway with a rhodium(ii) porphyrin metalloradical.
