Synthesis, Characterization, and Catalytic Activity of Iron(II) and Nickel(II) Complexes Containing the Rigid Pentadentate Ligand PY₅Me₂

Abstract

(2)]. The crystal structure of 2 was determined by X-ray crystallography. The catalytic activities of 1 and 2 towards the alcohol oxidation and

Molecular iron complexes as catalysts for selective C–H bond oxygenation reactions

“…Xiang and co-workers reported the synthesis of an iron complex bearing the rigid pentadentate N-donor ligand 33. 102 Cyclohexane is oxidised with 25% yield with respect to H 2 O 2 and an A/K ratio of 1.3, pointing to the presence of free radicals during the reaction (Table 1).…”

“…Xiang and co-workers reported the synthesis of an iron complex bearing the rigid pentadentate N-donor ligand 33. 102 Cyclohexane is oxidised with 25% yield with respect to H2O2 and an A/K ratio of 1.3, pointing to the presence of free radicals during the reaction (Table 1). Unusual iron complexes bearing hexadentate ligands (34a and 34b, Figure 5) have been prepared by Banse and co-workers and reacted readily with peracids to form high-valent iron(IV)-oxo species that could be isolated and characterized spectroscopically.…”

Synthesis, characterization and solution behavior of a systematic series of pentapyridyl-supported RuII complexes: comparison to bimetallic analogs

“…28–32 In addition to being utilized to support monometallic 33,34 and heterobimetallic 35–43 structures, this ligand has recently been shown to support silver nitrene transfer catalysts 44 and iron/nickel oxidation catalysts. 45,46 There are only two existing reports on ruthenium–Py 5 Me 2 complexes. In a 2014 study published by Kojima and coworkers, 47 Ru II −aquo and Ru III −hydroxo complexes were investigated and a Pourbaix diagram was presented for the Ru II/III couple.…”
