Electrochemically mediated decarboxylative acylation of N-nitrosoanilines with α-oxocarboxylic acids

A novel and ultrasensitive electrochemical DNA biosensor for pralatrexate detection

“…Cobalt oxide (Co 3 O 4 ) has been shown to have appreciable reversible redox capacity, semiconductivity, huge specic area, excellent catalytic behavior, long life, chemical stability and notable corrosion resistance, 21,22 thus becoming a suitable material for the construction of batteries, catalysts, sensors, supercapacitors and electronic devices. [23][24][25][26] There are useful approaches to boost the gas sensing activity of Co 3 O 4 , one of which is to build microstructures with merits for promotion of surface chemical responses.…”

Electrocatalytic ring-opening dihydroalkoxylation of N-aryl maleimides with alcohols under metal- and oxidant-free conditions

“…12 On the other hand, organic electrochemistry, which drives redox processes with electric current, has been proven to be a powerful synthetic tool in organic chemistry due to its prominent advantages, namely mild reaction conditions, easy reaction process control, high material utilization, and low energy consumption. 13 As part of our efforts to continuously develop cheap and eco-friendly catalytic methods under electrochemical conditions, 14 we herein describe the electrocatalytic ring-opening dihydroalkoxylation of N -aryl maleimides with alcohols under metal- and oxidant-free conditions. This electrochemical process consists of anodic single-electron transfer oxidation, cathodic radical reduction, rearrangement-ring cleavage and nucleophilic addition cascade, which employs tetrabutylammonium bromide not only as a redox catalyst but also as an efficient supporting electrolyte, and offers a practical and environmentally friendly route to ring-opening dihydroalkoxylation products (Scheme 1c).…”

Electrochemical C–H functionalization to synthesize 3-hydroxyalkylquinoxalin-2(1H)-ones via quinoxalin-2(1H)-ones and aldehydes

“…13 Organic electrosynthesis realizes redox reactions through the gain and loss of electrons to generate highly reactive intermediates and then complete various chemical transformations, which use electrons as reagents. 14 The electrolysis strategy can avoid the use of heavy metal catalysts and stoichiometric oxidants, and does not require pre-functionalized substrates. 15 At present, aldehydes can be reduced to hydroxyl radicals under electrochemical conditions and eventually converted into alcohols by radical coupling or addition of unsaturated compounds or CO 2 .…”
