Abstract

fetched live from OpenAlex

The silver complex of an abnormally bound, anionic N-heterocyclic carbene (NHC) can be transmetalated to ruthenium. The resulting ruthenium complexes are rare examples of anionic NHCs on ruthenium. Although Ru binding to the abnormal position of the carbene is observed in the complexes Ru(IDipp-BF3)(p-cymene)(L)Cl (IDipp-BF3=1,3-(2,6-iPr2C6H3)2-2-BF3(C3HN2)-4-yl), abstraction of chloride results in the unprecedented binding of the carbene via the methine position of the IDipp-BF3 ligand. For more information, see the Communication by D. W. Stephan and C. Pranckevicius on page 6597 ff.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
