The reaction of the ambident anion (2) derived from 2-cyano-3-ethyl-1-methyl-Δ3-piperideine (1) with t-butyl halides and p-NO2C6H4CH2X led to formation of the C-2 product (3) and the C-4 product (6) respectively via a probable single electron transfer reaction; dimerization of anion (2) gave dimers (8), (9), and (10) by electron transfer to m-dinitrobenzene, I2, and 2-methyl-2-nitropropane.

Employing UV picosecond (266 nm, 22 ps, ca. 0.5 mJ) and nanosecond (266 nm, 12 ns, 0.5-5 mJ) excitation, we have investigated the dynamics of the photodecarboxylation of p-nitrophenylacetate anions in aqueous solution.In agreement with previous micosecond flash photolysis studies, we believe that the primary decarboxylation products are the p-nitrobenzyl anion and carbon dioxide.It is proposed that the anion is produced in its triplet state following photoadiabatic cleavage of the lowest n,?* triplet state of p-nitrophenylacetate.The triplet state of the anion is observed as an intermediate (λmax ca. 290 nm) of lifetime 90 ns (pH > 5.0).In methanol/water and acetonitrile/water mixtures, its lifetime is found to increase as the aqueous portion of the solvent is decreased.A reaction mechanism is developed.
Palladium and Nickel Catalyzed Suzuki Cross-Coupling with Alkyl Fluorides
Balaraman, Kaluvu,Wolf, Christian
supporting information, p. 8994 - 8999 (2021/11/20)
Suzuki cross-coupling of benzylic and unactivated aliphatic fluorides with aryl- and alkenylboronic acids has been achieved via mechanistically distinct Pd and Ni catalyzed pathways that outperform competing protodeboronation, β-hydride elimination, and h

In this study, 4-nitrobenzyl bromide was used as a catalyst for reduction of CO2 and as an initial substrate for electrosynthesis of 4-nitrophenylacetic acid. Cu nanoparticles/Pd nanoparticles/reduced graphene oxide nanocomposite modified glassy carbon electrode (Cu/Pd/rGO/GCE) was used to promote electroactivation of CO2. rGO film was fabricated via electrochemical reduction of dispersed GO nanosheets on the GCE surface. Cyclic voltammetry procedure was applied in two steps to deposit Pd and Cu nanoparticles on the rGO/GCE surface. The morphology and structure of the nanocomposites were characterized using FESEM, EDS, AFM and XRD analysis. FTIR, 1H and 13C NMR spectral characteristics were used to identify the final products of the catalytic process. The electrocarboxylation of 4-nitrobenzyl bromide occurs at a potential which is less negative than those reported for other aryl halides. The results indicate that 4-nitrobenzyl bromide, as a catalyst, plays a dual role in the electrosynthesis of 4-nitrophenylacetate. The dual role includes the electrocatalytic reduction of CO2 and reaction of produced CO2 ?? with 4-nitrobenzyl bromide radical anion. Finally, an EC'C mechanism is proposed for the electrosynthesis of 4-nitrophenylacetate.
