An electrosynthesis of sulphones

Journal of Applied Electrochemistry, 1973
The cathodic reduction of SO2, dissolved in aprotic solvents, to the anion radical SO2− in the presence of organic halides RX results in the formation of organic sulphones R-SO2-R at appreciable current yields. With dihalides, polymeric sulphones or, as in the case ofo-xylylenedibromide, inner sulphinic esters (sultines) are formed, the latter being ...

Electrosynthesis of ammonia

Nature, 1985
Since Chatt and co-workers first reported that the protolysis of the dinitrogen complex cis-[W(N2)2(PMe2Ph)4] gives ammonia1, cis-[W(N2)2(PMe2Ph)4]H+→ 2NH3 + N2 + degradation products (1) there has existed the engaging possibility that a cyclic conversion of molecular nitrogen to ammonia might be achieved at room temperature and pressure using ...

Electrosynthesis of Protected Dehydroamino Acids

Organic Letters, 2023
A NaCl-mediated electrochemical oxidation of amino acid carbamates (R1 = Boc, Cbz) afforded α-methoxylated α-amino acids. Subsequent acid-catalyzed elimination delivered valuable dehydroamino acid derivatives. The simplicity of our setup using graphite-electrodes was showcased, producing N-Boc-ΔAla-OMe on a decagram scale.

Electrosynthesis of 1,2,4-Triazolium Tetrafluoroborates

Organic Letters, 2021
The synthesis of 1,2,4-triazolium tetrafluoroborates under electrochemical conditions is reported. The reaction is performed with stoichiometric amounts of HBF4, which converts starting materials to their corresponding cationic forms due to protonation.

IoT-based electrosynthesis ecosystem

Internet of Things, 2018
Abstract In this paper, we presented the electrosynthesis ecosystem using esp8266 with OTA compilation integrated, the MQTT Broker for the control system that would be installed on a Raspberry Pi and MQTT protocol for the wireless data transfer layer which provides the electrosysnthesis machine to work 24/7 and with the AI that can be implemented ...

Paired Electrosynthesis of Cyanoacetic Acid

The Journal of Organic Chemistry, 2004
Cyanoacetic acid is formed by cathodic reduction of CO(2) and anodic oxidation of the tetraalkylammonium salt anion; the process is conduced in acetonitrile using a divided cell with a medium porosity glass-frit diaphragm. A mechanism for this paired electrochemical reaction is proposed.

Parallel Electrosynthesis of 1,2-Diamines

Journal of Combinatorial Chemistry, 2001
Parallel reductive hydrocoupling of aldimines was performed to generate vicinal diamines using the spatially addressable electrolysis platform (SAEP). The stainless steel cathodes and sacrificial aluminum anodes were used in this electrosynthesis methodology.
