Abstract
[86609-17-8] C20H16CuMn2N4O8 (MW 613.79) InChI = 1S/2C10H8N2.Cu.2Mn.8O/c2*1-3-7-11-9(5-1)10-6-2-4-8-12-10;;;;;;;;;;;/h2*1-8H;;;;;;;;;;;/q;;+2;;;;;;;;;2*-1 InChIKey = MFJBERCSDXBHFL-UHFFFAOYSA-N (oxidant, used for the oxidation of thiols to disulfides,1 benzylic alcohols to carbonyl compounds,2 aromatic amines to azo compounds,2 benzylamine and oximes to the corresponding carbonyl compounds2) Alternate Name: bis(2,2-bipyridine-N,N′)copper(2+) permanganate. Physical Data: purple solid; decomposes at 105–110 °C.2 Solubility: sol water, acetone, and methylene chloride.2 Analysis of Reagent Purity: λmax (log ε) (H2O): 290 nm (4.50), 296 (4.59), 306 (4.58), 458, (3.23), 474 (3.28), 491 (3.38), 510 (3.49), 529 (3.57), 552 (3.54), 576 (3.35). Preparative Method: Potassium Permanganate (0.01 mol) dissolved in a minimum of water is added to bis(2,2′-bipyridyl)copper(II) chloride (0.02 mol) in water (25 mL). On cooling a purple precipitate is collected and air dried.2 The yield is 95%. Handling, Storage, and Precautions: oxidant, store in a glass vessel at or below rt. The reagent should be filtered and dried on a filter paper, not on a sintered glass funnel. It should be transferred with nonmetallic spatulas; if metallic spatulas are used the reagent may burst into flame.1

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.
