Electrochemical oxidation of cholesterol
Beilstein J. Org. Chem. 2015, 11, 392–402, doi:10.3762/bjoc.11.45
- cholesterol took place in the cathodic compartment. The oxidation did not occur without the electrochemical reduction of Tl(III), which suggests that Tl(III) cannot activate dioxygen. In addition, the replacement of dioxygen by hydrogen peroxide gave a mixture of oxidation products. This indicates that
Stereoselective cathodic synthesis of 8-substituted (1R,3R,4S)-menthylamines
Beilstein J. Org. Chem. 2015, 11, 294–301, doi:10.3762/bjoc.11.34
- stereoselectivity of the following electrochemical reduction process (Scheme 3, step 3). Concomitantly, the resulting amines 1 are expected to have improved properties as catalysts/auxiliaries for asymmetric transformations due to the increased sterical demand in the vicinity of the amine group. Results and
- (6c and 7c, R2 = Ph) require prolonged reaction times and render slightly lower yields. Electrochemical reduction of 8-substituted menthone oximes The electrolyses were carried out in a divided cell using a Nafion® sheet as separator and platinum as anodic material. Since previous studies revealed

Effect of temperature onto yield and stereoselectivity of the electrochemical reduction of 7a on a lead cathode. Influence of alkylammonium salts on the
Cathodic reductive coupling of methyl cinnamate on boron-doped diamond electrodes and synthesis of new neolignan-type products
Beilstein J. Org. Chem. 2015, 11, 200–203, doi:10.3762/bjoc.11.21
- product [8]. In our second investigation on the use of the BDD electrode in organic synthesis, the electrochemical reduction of methyl cinnamate (1a) was investigated to assess the applicability of BDD electrodes under cathodic reduction conditions, and to obtain new neolignan-type bioactive substances
An integrated photocatalytic/enzymatic system for the reduction of CO2 to methanol in bioglycerol–water
Beilstein J. Org. Chem. 2014, 10, 2556–2565, doi:10.3762/bjoc.10.267
- electrochemical reduction of the complex. Selective reduction of NAD+ to 1,4-NADH has also been experimentally evidenced by 1H NMR and HPLC measurements. Finally, the enzymatic route of the CO2 reduction was confirmed to occur as was previously described [7][11]. The novelty of the photochemical NADH regeneration
Electrocarboxylation: towards sustainable and efficient synthesis of valuable carboxylic acids
Beilstein J. Org. Chem. 2014, 10, 2484–2500, doi:10.3762/bjoc.10.260
- Electrochemical reduction is an efficient approach to activate thermodynamically stable CO2 under relatively mild and safe conditions. Electrocarboxylation allows the production of valuable carboxylic acids, through incorporation of CO2 in a wide range of organic chemicals. This way, polymer building blocks are
Visible light photoredox-catalyzed deoxygenation of alcohols
Beilstein J. Org. Chem. 2014, 10, 2157–2165, doi:10.3762/bjoc.10.223
- substitution pattern of benzoates we intended to shift the electrochemical reduction potentials of the substances into a region that could be accessed by common visible light photocatalysts. The substituents should be as inert as possible in order not to interfere with the photochemical reaction itself
Novel indolin-2-one-substituted methanofullerenes bearing long n-alkyl chains: synthesis and application in bulk-heterojunction solar cells
Beilstein J. Org. Chem. 2014, 10, 1121–1128, doi:10.3762/bjoc.10.111
- nine different n-alkyl substituents. Their optical absorption and the first electrochemical reduction potential are close to those of PCBM. The lengthening of the n-alkyl radical at the nitrogen atom results in a gradual increase in the AIM solubility. The photovoltaic properties of PSCs based on the
Tuning the interactions between electron spins in fullerene-based triad systems
Beilstein J. Org. Chem. 2014, 10, 332–343, doi:10.3762/bjoc.10.31
- are crucial for the application of fullerene triads were investigated by EPR spectroscopy as fluid and frozen solutions at room temperature and 77 K, respectively, following electrochemical reduction. Whilst these triads are capable of accepting multiple electrons into each of the fullerene groups, we
- electrochemical reduction at −1.4 V of 0.5 mM solutions of compound in o-dichlorobenzene containing [n-Bu4N][BF4] as the supporting electrolyte. Fluid solution EPR spectra of 12−, 42− and 71− (Figure 3) are similar in g value (2.0002, 2.0001 and 2.0000, respectively) but differ in linewidth (ΔHp−p 1.1, 1.3 and
Aromatic and heterocyclic perfluoroalkyl sulfides. Methods of preparation
Beilstein J. Org. Chem. 2010, 6, 880–921, doi:10.3762/bjoc.6.88
- developed (see sections 4.1.1.–4.1.4.), e.g., the electrochemical reduction of perfluoroalkyl halogenides [173][181]. In the presence of thiolate anions the resulting electrophilic radicals react [182][183] to give aryl perfluoroalkyl sulfides (Table 9). The good yields for electrochemical
- ]. Electrochemical studies involving the SO2−• radical anion prove that the electron transfer to CF3Br takes place at a reduction potential of the mediator between −0.9 and −1.0 V which prevents the transfer of a second electron to CF3• and the generation of CF3− [199]. Therefore electrochemical reduction in the

Beilstein J. Org. Chem. 2009, 5, No. 1, doi:10.3762/bjoc.5.1
- reaction; would the analogous chemistry be seen with TDAE where no sulfur atoms are present? The experiments were of heightened interest because of the recent report by Andrieux and Pinson [60] on the standard reduction potential of the phenyl radical (formed by electrochemical reduction of the
