A comparative study of anodic fluorination of N-alkyl and N,N-dialkyl phenylacetamides in Et3N·4HF medium

Intriguing Catalytic Activity of Surface Active Gold‐Platinum Islands on Nano‐Porous Au in Determining Efficient Direct Formic Acid Oxidation Pathway

“…The marginal shift observed in the present case, may also due to the lesser 'x' values (i. e. < 5 %) well beyond the XRD technique detection limit. The XPS studies of Au 100-x Ag 2x /C and Au 100-x Pt x /C nano-materials were carried out and their deconvoluted spectra [39] are presented in Figure 3 and SI, Figure (S1& S2)). Figure 3(A) shows one set of peaks for Au 4f 7/2 and Au 4f 5/2 energy levels at around 83.82 eV & 87.28 eV ascribed to metallic Au.…”

Galvanostatic and potentiostatic fluorination of 2-indanone, 1-indanone and 1,3-indandione in Et3N · 4HF medium. Adsorption effects on yield and product selectivity

“…Hence in the present study, the voltammetric behaviour of indanones are reported on glassy carbon electrodes, while the preparative studies are reported using the conventional platinum anodes and cathodes. Similar approach was also adopted earlier during the SEF of N-alkyl and N,N dialkyl phenylacetamides [10].…”

“…Since, it has been shown earlier that potentiostatic approach gives better selectivity in such compounds which posses relatively high oxidation potential, both potentiostatic and galvanostatic methods were evaluated [10]. Since Pt electrodes exhibited lower anodic limit, cyclic voltammteric measurements are reported in Pt as well as glassy carbon electrodes.…”

“…Since Pt electrodes exhibited lower anodic limit, cyclic voltammteric measurements are reported in Pt as well as glassy carbon electrodes. In the earlier investigations, it was noticed that even on a Pt electrode, constant potential electrolysis needs to be carried out at a potential which is substantially higher than the oxidation peak potential observed on glassy carbon electrode [10]. To understand this observation, some chronoamperometric investigations on Pt electrodes in the absence and in presence of reactant molecule were also carried out.…”

The Fascinating Chemistry of α‐Haloamides

“…The introduction of fluorine atoms at the α‐position of amides deserves special attention because it may lead to unprecedented or modified biological properties of the target molecule. Noel and co‐workers first exploited organic electrochemistry as an environmentally friendly method for achieving the α‐fluorination of N ‐alkyl and N,N ‐dialkyl phenylacetamides . Specifically, it was observed that under potentiostatic conditions the electrolysis led to predominantly side chain fluorination at the active methylene group, while nuclear fluorination was predominant under galvanostatic conditions (Scheme ).…”
