Abstract

fetched live from OpenAlex

Reaction of LCoCH 2 SiMe 3 (L = 2,6-bis[2,6-dimethylphenyliminoethyl]pyridine) with H 2 produces LCo(N 2 ), presumably via intermediate LCoH. Reaction of LCo(N 2 ) (prepared in this way or via reaction of LCoCl 2 with Na/Hg) with aryl halides ArX (X = Cl, Br, I) produces LCoAr and LCoX in a ratio depending on the nature of Ar and X. For X = Cl, the reaction is slowest but also produces the largest amount of LCoAr. Electron-withdrawing substituents both accelerate the reaction and improve the yield of LCoAr. Computational studies support a radical mechanism for this reaction, involving displacement of N 2 to give LCo(XAr) followed by loss of the Ar radical, which then binds to a second Co(0) moiety.

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.
