A facile and efficient direct electrochemical oxidation method for C−3 phosphorylation of 2H-indazoles with trialkyl phosphites as the phosphorylation reagents has been developed. Introducing electricity to the green and sustainable synthetic procedures allowed the reactions to be carried out under simple and mild conditions without any metal salts and additional oxidants. Electrochemical data showed that the cation radical species which were generated from the oxidation of 2H-indazoles were stabilized by 1,1,1,3,3,3-hexafluoro-2-propanol and could be captured by trialkyl phosphites effectively to form C−3 phosphorylated 2H-indazoles. In an undivided cell, a board range of functional groups on various substrates were well tolerated and the yield of the desired phosphorylated products was up to 84%. Moreover, a plausible mechanistic proposal involving radical pathway was established based on the results of cyclic voltammetry, in situ FTIR and control experiments.

“…[ 24,25 ] The bands at 1420 and 1345 cm −1 show the coupling of the pyridiniumium to carbonyl‐containing reactants. [ 25–27 ] The bands at 1263, 1191, 1020, 824, 776, and 680 cm −1 are assigned to CCl vibrations, CH bending vibrations, pyridiniumium ring vibrations, CH out of plane bending vibrations, ring deformation, and coupled pyridiniumium associated vibrations, respectively.

Using a combined theoretical and experimental approach, a mechanistic understanding of the interactions and pseudocapacitance of different quinone‐coupled viologen and pyridiniumium molecules sandwiched between titanium carbide (Ti3C2Tx) MXene layers has been provided. Three different derivatives of quinone‐coupled viologen and pyridiniumium are synthesized using nucleophilic substitution reaction and subsequently hybridized with Ti3C2Tx MXene (organic@Ti3C2Tx) using self‐assembly approach. The atomic structure of pristine Ti3C2Tx and organic@Ti3C2Tx hybrid films is investigated using grazing incidence X‐ray diffraction and X‐ray pair distribution function analysis using synchrotron radiation. Spectroscopic results confirm the coupling of quinones with viologen and pyridiniumium molecules and their non‐covalent functionalization to the MXene without their catalytic decomposition. First‐principles calculations confirm that the preferred orientation of organic molecules upon intercalation/adsorption is horizontal to the Ti3C2Tx surface. The authors reveal that these molecules attach to the Ti3C2Tx surface with a significantly high binding energy (up to −2.77 eV) via a charge transfer mechanism. The electronic structure calculations show that all organic@Ti3C2Tx hybrids preserved their metallic behavior. Free‐standing organic@Ti3C2Tx hybrid films show a more than three times higher capacitance at ultra‐high scan rates (up to 20 V s−1) compared to their pristine counterpart due to molecular pillaring of organic molecules between Ti3C2Tx layers via strong binding energies and charge transfer.
