Abstract
Electrocatalytic transformations giving rise to new C-C bond formation and new products is of value. We have recently discovered that phenolic compounds undergo selective electrochemical oxidation giving rise to reactive phenoxyl radicals which combine to produce a product with new C-C bond formed [1]. Five phenolic compounds including butylated hydroxytoluene (BHT), 4- tert -butylphenol (4TBP), 2- tert -butylphenol (2TBP), 2,4,6-tri- tert -butylphenol (TTBP), and 2,6,-di- tert -butylphenol (DTBP) were systematically evaluated by electrochemical methods to determine their oxidation/reduction potentials as a function of concentration. At identical experimental conditions, only DTBP exhibited electrochromic behavior which was dependent on concentration and electrochemical cycling. The electrocatalytic oxidation of DTBP resulted in a formation of a new compounds due to C-C coupling. The reaction was monitored by electrochemical methods, UV-vis spectroscopy and final product characterized by X-ray diffraction. Recently, we expanded the electrocatalysis to include diverse phenolics such as dihydroxybiphenol (DHBP) which also formed a yellow-coloured solution, indicating a product formation. The electrochemical and spectroscopic characterization of DHBP reaction will be described. References Zabik, N., Virca, C. N., McCormick, T., Martic-Milne, S. (2016).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
