Abstract
[144026-79-9] C3F9O9S3Sc (MW 492.16) InChI = 1S/3CHF3O3S.Sc/c3*2-1(3,4)8(5,6)7;/h3*(H,5,6,7);/q;;;+3/p-3 InChIKey = HZXJVDYQRYYYOR-UHFFFAOYSA-K (a Lewis acid catalyst) Physical Data: mp >300 °C. Solubility: soluble in H2O, alcohol, acetonitrile, and most polar organic solvents. Form Supplied in: colorless solid. Preparative Methods: 1scandium triflate is commercially available. On the other hand, it can also be prepared from the corresponding oxide (Sc2O3) and aqueous trifluoromethanesulfonic acid (TfOH). After filtration and concentration of the clear aqueous solution in vacuo, the resulting hydrated salt is dried in vacuo (<1 mmHg) at 200 °C for 40 h to afford the anhydrous triflate, which is stored over P2O5. Handling, Storage, and Precautions: the anhydrous triflate is fairly hygroscopic (not decomposed, forms a hydrate) and must be kept in a desiccator over P2O5 and freshly dried in vacuo (< 1 mmHg) at 200 °C for 1 h before using.
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.
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.
