Redox Noninnocent Azo-Aromatic Pincers and Their Iron Complexes. Isolation, Characterization, and Catalytic Alcohol Oxidation

Redox Noninnocent Azo-Aromatic Pincers and Their Iron Complexes. Isolation, Characterization, and Catalytic Alcohol Oxidation

The new redox-noninnocent azoaromatic pincers 2-(arylazo)-1,10-phenanthroline (L1) and 2, 9-bis(phenyldiazo)-1,10-phenanthroline (L2) and their iron complexes are reported. L1 is a tridentate pincer having an NNN donor set, whereas L2 is tetradentate, having two azo-N donors and two N-donor atoms from the 1,10-phenanthroline moiety. Electronic structures of the iron(II) complexes and their reduced and oxidized forms are elucidated, and pentacoordinated [Fe(L1,2)Cl2] were successfully used as catalysts for the aerobic oxidation of primary and secondary benzylic alcohols under ambient conditions.
