Abstract

fetched live from OpenAlex

[23708-48-7] C5H10Br2Mg2 (MW 278.55) InChI = 1S/C5H10.2BrH.2Mg/c1-3-5-4-2;;;;/h1-5H2;2*1H;;/q;;;2*+1/p-2 InChIKey = OUEGHZYBWJTUAD-UHFFFAOYSA-L (constructing block agent: transformation of many functional groups into cyclohexane, spiro[4.5]decane, and spiro[5.5]undecane synthetic intermediates, and α,ω-difunctional compounds) Physical Data: d 0.999 g cm−3. Solubility: sol THF, ether, and toluene. Form Supplied in: the reagent is available in THF (0.5 M). Analysis of Reagent Purity: titration.2 Handling, Storage, and Precautions: solutions are highly flammable; must be stored in the absence of proton sources, carbon acids, and oxygen. Flasks should be flushed with dry Ar or N2. Handle with standard syringe technique to prevent contact of the solutions with oxygen and moisture.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
