Abstract
[32248-43-4] I2Sm (MW 404.16) InChI = 1/2HI.Sm/h2*1H;/q;;+2/p-2/f2I.Sm/h2*1h;/q2*-1;m InChIKey = UAWABSHMGXMCRK-ZFDXCKRNCZ (one-electron reducing agent possessing excellent chemoselectivity in reduction of carbonyl, alkyl halide, and α-heterosubstituted carbonyl substrates;1 promotes Barbier-type coupling reactions, ketyl–alkene coupling reactions, and radical cyclizations1) Physical Data: mp 527 °C; bp 1580 °C; d 0.922 g cm−3. Solubility: soluble 0.1M in THF. Form Supplied in: commercially available as a 0.10 M solution in THF. Preparative Methods: typically prepared in situ for synthetic purposes. SmI2 is conveniently prepared by oxidation of Samarium(0) metal with organic dihalides.2 Handling, Storage, and Precautions: is air sensitive and should be handled under an inert atmosphere. SmI2 may be stored over THF for long periods when it is kept over a small amount of samarium metal.
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.
