Scanning Electrochemical Microscopy. 33. Application to the Study of ECE/DISP Reactions

The scanning electrochemical microscope (SECM) is used to measure the kinetics of ECE/DISP type reactions.The theory of the steady-state feedback response is developed in terms of numerical simulation.The theoretical curves show that the variation of the tip and substrate current with the tip-substrate separation can readily be used to differentiate between an ECE and a DISP1 pathway.The theoretical results suggest that rate constants up to 1.6E5 s-1 can be measured with tip sizes usually employed in SECM.The theory is validated using the experimental example of the reduction of anthracene in DMF in the presence of phenol.The reaction is shown to follow a DISP1 pathway, in agreement with previous studies.Good agreement is found between theory and experiment for all the phenol concentrations explored, and a rate constant of (4.4 +/- 0.4)E3 M-1 s-1 has been determined for the protonation of the anthracene radical anion by phenol.

A novel Birch reduction of aromatic compounds using aqueous titanium trichloride: Anions of trans-10b,10c-dimethyl-2,7,10b,10c-tetrahydropyrene

The Birch reduction of 10b,10c-dimethyl-10b,10c-dihydropyrene 1 and anthracene could be predicted on the basis of their reduction potentials and achieved readily with aqueous titanium trichloride in near quantitative yields. Controlled reduction of a nitro group could be achieved under these conditions with the aromatic hydrocarbon remaining intact. The anion derived from the hexane obtained from reduction of 1 provided synthetic routes to derivatives of 1 inaccessible from direct substitution reactions of 1. Oxidative dimerization of the anion led to the formation of a series of interesting products.

A facile and versatile electro-reductive system for hydrodefunctionalization under ambient conditions

A general electrochemical system for reductive hydrodefunctionalization is described, employing the inexpensive and easily available triethylamine (Et3N) as a sacrificial reductant. This protocol is characterized by facile operation, sustainable conditions, and exceptionally wide substrate scope covering the cleavage of C-halogen, N-S, N-C, O-S, O-C, C-C and C-N bonds. Notably, the selectivity and capability of reduction can be conveniently switched by simple incorporation or removal of an alcohol as a co-solvent.

Conversion of Aryl Aldehydes to Benzyl Iodides and Diarylmethanes by H3PO3/I2

For the first time, H3PO3 was used as both the reducing reagent and the promotor in the reductive benzylation reactions with aryl aldehydes. By using a H3PO3/I2 combination, various aromatic aldehydes underwent iodination reactions and Friedel-Crafts type reactions with arenes via benzyl iodide intermediates, readily producing benzyl iodides and diarylmethanes in good yields. Intramolecular cyclization reactions also took place, giving the corresponding cyclic compounds. This new strategy features easy-handling, low-cost, and metal-free conditions.

The invention belongs to the technical field of organic chemical synthesis. The method comprises the following steps: (1) mixing the carbonyl compound and the amine compound in a solvent, reacting 3 - 6 under the illumination of 380 - 456 nm, the reaction system is low in toxicity, high in atom utilization rate 12 - 24h. and production efficiency, safe and controllable in reaction process and capable of simplifying the operation in the preparation and production process. At the same time, the residue toxicity of the reaction is minimized, the pollution caused by the production process to the environment is reduced, and the steps and operations of removing residues after the reaction are simplified. In addition, the reactant feedstock is readily available. The reactant does not need additional modification before the reaction, can be directly used for preparing production, simplifies the operation steps, and shortens the reaction route. The production cost is obviously reduced.

Noble metal nanoparticles stabilized by hyper-cross-linked polystyrene as effective catalysts in hydrogenation of arenes

This work is addressing the arenes’ hydrogenation—the processes of high importance for petrochemical, chemical and pharmaceutical industries. Noble metal (Pd, Pt, Ru) nanoparticles (NPs) stabilized in hyper-cross-linked polystyrene (HPS) were shown to be active and selective catalysts in hydrogenation of a wide range of arenes (monocyclic, condensed, substituted, etc.) in a batch mode. HPS effectively stabilized metal NPs during hydrogenation in different medium (water, organic solvents) and allowed multiple catalyst reuses.
