Abstract

fetched live from OpenAlex

[1493-01-2] CHFI2 (MW 285.8260) InChI = 1S/CHFI2/c2-1(3)4/h1H InChIKey = RIHYOLCRHKZJPJ-UHFFFAOYSA-N (reagent for monofluorocyclopropanation) Physical Data: bp 100.3 °C, mp −34.5 °C. Handling and Storage: amber color liquid that can be stored at room temperature in the absence of light. Preparative Methods: fluorodiiodomethane can be prepared by the Finkenstein reaction of dibromofluoromethane with sodium iodide in acetone.1 The reaction affords the reagent in 25% yield after distillation under reduced pressure (eq 1). (1) Iodoform reacts with 0.4 equiv of mercuric fluoride at 120 °C to afford fluorodiiodomethane after distillation in 56% yield.2 This reaction was used to prepare large quantities of the reagent (eq 2).

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.
