Selective CF Bond Activation of Tetrafluorobenzenes by Nickel(0) with a Nitrogen Donor Analogous to N‐Heterocyclic Carbenes
Bibliographic record
Abstract
Abstract NHC? Nein, nur N! Ein neutraler, basischer und stark σ‐donierender Stickstoffligand mit ähnlichen Eigenschaften wie N‐heterocyclische Carbene (NHCs) ermöglicht oxidative Additionen schwieriger Substrate an späte Übergangsmetalle. Bei Raumtemperatur wurde für Hexa‐, Penta‐ und alle drei Isomere von Tetrafluorbenzol mit einer Nickel(0)‐Quelle in Gegenwart dieses Liganden eine selektive C‐F‐Aktivierung beobachtet. magnified image

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.
