Determination of the lifetimes of unstable ion radicals by homogeneous redox catalysis of electrochemical reactions. Application to the reduction of aromatic halides

Electrochemical and homogeneous electron transfers to the Alzheimer amyloid-β copper complex follow a preorganization mechanism

“…Two examples are given in Fig. 4, which shows the cyclic voltammetric catalytic responses (43,44) resulting from the homogeneous reaction of Cu(Aβ) complex with the ½OsðbpyÞ 2 ðpyÞCl 2þ∕þ and ½OsðdmbpyÞ 2 Cl 2 þ∕0 complexes (py: pyridine, bpy: 2,2′ bispyridine, dmbpy: 4,4′-dimethyl-2,2′-bipyridine). In the first case, the thermodynamics is in favor of the reaction of the Os III complex with the Cu I complex, and vice versa in the second case.…”

Electroreductive Radical Cyclization of Ethyl 2‐Bromo‐3‐allyloxy‐ and‐3‐(propargyloxy)propanoates Catalyzed by (Tetramethylcyclam)nickel(I) Electrogenerated at Carbon Cathodes in Dimethylformamide

“…Considerable evidence exists that DMF can act as a hydrogen atom donor. [37][38][39][40] An inevitable consequence of electrolytic reductions in DMF is that small quantities of electrogenerated bases are produced. [41] Under such conditions, 3 can undergo deprotonation, due to the acidity of the proton adjacent to the carbonyl moiety, to give the corresponding resonance-stabilized carbanion 11; protonation of this carbanion results in the formation of 4 [reaction (4)].…”

Electrosynthesis and characterization of a poly(paraphenylene) deriving from p-fluoroanisole

“…In fact, little is known about the anodic behavior of these compounds, particularly in connection with electropolymerization. Contrarily, the cathodic reduction is well documented and has very often given the cleavage of the carbon-halogen bond [24][25][26][27].…”
