Proton-coupled electron transfer (PCET) reactions are fundamental to energy transformation reactions in natural and artificial systems and are increasingly recognized in areas such as catalysis and synthetic chemistry. The interdependence of proton and electron transfer brings a mechanistic richness of reactivity, including various sequential and c...
Proton-coupled electron transfer (PCET) was studied in a series of tungsten hydride complexes with pendant pyridyl arms ([(PyCH2Cp)WH(CO)3], PyCH2Cp = pyridylmethylcyclopentadienyl), triggered by laser flash-generated RuIII-tris-bipyridine oxidants, in acetonitrile solution. The free energy dependence of the rate constant and the kinetic isotope ef...
Metal hydrides are key intermediates in catalytic proton reduction and dihydrogen oxidation. There is currently much interest in appending proton relays near the metal centre to accelerate catalysis by proton-coupled electron transfer (PCET). However, the elementary PCET steps and the role of the proton relays are still poorly understood, and direc...
Proton-coupled electron transfer (PCET) reactions are a kind of unconventional redox reactions, which exhibit special reactivity and selectivity due to their unique interdependent electron-proton transfer mechanism. There are three possible pathways of PCET processes, including stepwise electron transfer followed by proton transfer (ETPT), proton t...
Positron emission tomography (PET) is an important technique for the early diagnosis of disease. Due to the specific physical and chemical properties of Fluorine-18, this important isotope is widely used in PET for labelling and molecular imaging, and its introduction into medicine molecules could produce PET tracers. Developing with the developmen...
[FeFe(Cl2‐bdt)(CO)6] (1) (Cl2‐bdt = dichlorobenzene‐1,2‐dthiolate), inspired by the active site of FeFe‐hydrogenase, shows a chemically reversible 2e‐ reduction at ‐1.20 V vs. Fc+/Fc. The rigid and aromatic bdt‐bridging ligand lowers the reduction potential and stabilizes the reduced forms, compared to analogous complexes with aliphatic dithiolates...
A Cu-catalyzed trifluoromethylthiolation of primary and secondary alkylboronic acids with an electrophilic trifluoromethylthiolating reagent is described. Tolerance for a variety of functional groups was observed.
Development of transition-metal-catalyzed trifluoromethylation of arene substrates under mild reaction conditions has attracted great attention in the past few years. Among the many methods developed, copper-mediated trifluororomethylation has made significant progress and is the subject of this minireview.
The old one two: A sequential iridium-catalyzed borylation and copper-catalyzed trifluoromethylation of arenes is described (see scheme; Pin = pinacol). The reaction is conducted under mild reaction conditions and tolerates a variety of functional groups. The advantages of this tandem procedure are demonstrated by the late-stage trifluoromethylatio...
A copper-catalyzed trifluoromethylation of aryl- and alkenylboronic acids with Togni's reagent was described. The reaction proceeded in good to excellent yields for a range of different substrates including heteroarylboronic acids and substrates with a variety of functional groups under mild reaction conditions.
