Abstract
[931109-52-3] C10H10Cl3NO5S (MW 362.61) (reagent used as a metal nitrene precursor for CH insertion and aziridination reactions) Physical Data: mp 123 °C; 1H NMR (CDCl3) δ 8.14 (s, 1H), 7.90 (d, J = 8.43 Hz, 2H), 7.36 (d, J = 8.01 Hz, 2H), 4.65 (s, 2H), 2.46 (s, 3H); 13C NMR (CDCl3) δ 153.6, 146.5, 130.0, 129.9, 129.7, 94.1, 75.1, 21.8 Solubility: sol aromatic hydrocarbons (toluene, benzene, chlorobenzene), chloroform, dichloromethane, ethyl acetate; slightly soluble ether. Form Supplied in: white solid. Preparative Methods: N-tosyloxycarbamates are easily prepared from the corresponding chloroformate by treatment with hydroxylamine, followed by a standard tosylation reaction (eq 1). (1) Purification: recrystallized from a mixture of chloroform/hexanes (1/1) or flash chromatography on silica gel with 1% EtOAc/dichloromethane as eluent. Handling, Storage, and Precautions: stable at room temperature for up to 6 months; thermogravimetry analysis showed decomposition above 180 °C.
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.
