Abstract

fetched live from OpenAlex

[132799-16-7] C17H22F3IN2O3S (MW 518.33) InChI = 1S/2C8H11N.CHF3O3S.H2I/c2*1-6-4-7(2)9-8(3)5-6;2-1(3,4)8(5,6)7;/h2*4-5H,1-3H3;(H,5,6,7);1H2/q;;;+1/p-1 InChIKey = NHMJWSHZUNSWPD-UHFFFAOYSA-M (convenient source of iodonium ion, effective in activation of glycosyl donors such as thioglycosides and n-pentenyl orthoesters, iodination of exo-glycals, and acetal formation from vinyl ethers) Alternate Name: IDCT. Physical Data: crystalline solid. Solubility: soluble in dichloromethane and dichloroethane; insoluble in ether. Preparative Methods: prepared1 from the reaction of AgOTf with collidine in dichloromethane, followed by the addition of I2. The reaction mixture was filtered through Celite and crystallization was induced by the addition of ether. The resulting solid was filtered and dried in vacuo before use.

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.
