Iron versus ruthenium oxidation in 1,1′-bis(diphenylphosphino)ferrocene–ruthenium(II) complexes: EPR and spectroelectrochemical evidence

Invariant Oxidation State of Copper but not of Ruthenium in Complexes with Noninnocent N‐(2‐Methyl‐5,8‐dioxo‐5,8‐dihydroquinolin‐7‐yl)acetamide: A Combined Structural, Electrochemical and Spectroelectrochemical Investigation

“…Unambiguous identifica- tion of the expected band at around 600 nm for oxidation of dppf is difficult in the present case because of overlap with the MLCT band. [37] Figure 5). These bands are reminiscent of the bands observed in L ·-and are assigned to intraligand transitions thus corroborating the IR spectroelectrochemical results of a L-centered reduction in 1 · .…”

Synthesis and Characterization of Cerium and Yttrium Alkoxide Complexes Supported by Ferrocene-Based Chelating Ligands

“…While complexes of transition metals have been targeted before to study redox isomerism, 15,18,[20][21][22][23][24] lanthanide and actinide examples are still limited. 19,25 With a strongly oxidizing metal center like cerium(IV), there exists the potential for redox events to occur, effectively changing the ferrocene backbone of the ancillary ligand into ferrocenium upon complexation.…”

Heterobimetallic [Ru(II)/Fe(II)] complexes: On the formation of trans- and cis-[RuCl2(dppf)(diimines)]

“…The chemistry of dppf (1,1 0 -bis[diphenylphosphino]ferrocene) is well documented [11] and the interest in such species is mainly focused on structural [12,13], electrochemical [14,15] and catalytical [16,17] studies. This diphosphine is a very versatile ligand since it can be coordinated to a transition metal as a cis-chelate, trans-spanning and bridging, leading to a great diversity of structures and properties for its complexes [11].…”
