Electrochemical Behaviour of Nitrobenzene, Nitrosobenzene, Azobenzene, and Azoxybenzene on Hg, Pt, Cu, and Ni Electrodes in Aprotic Medium
Bibliographic record
Abstract
Abstract The electrochemical behaviour of nitrobenzene and other members of the nitrobenzene family (nitrosobenzene, azoxybenzene, azobenzene) has been investigated in DMF/TEAP by cyclic voltammetry, polarography, and controlled potential electrolysis at mercury, platinum, copper, and nickel cathodes. At the four electrodes, nitrobenzene and the other members of the family are reduced to aniline via hydrazobenzene upon exhaustive electrolysis at −2.35 V vs. Ag/AgNO3 (0,05 M). The electrochemical reversibility of the nitrobenzene/nitrobenzene radical anion and of the azoxybenzene/azoxybenzene radical anion couples is decreased by the presence of oxides at the surface of copper and nickel. The presence of oxides has little influence on the reversibility of the nitrosobenzene/nitrosobenzene radical anion and azobenzene/azobenzene radical anion couples.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
