Abstract

fetched live from OpenAlex

Oxidative addition of very robust C–F and C–O bonds has been accomplished in reactions of the aluminum(I) compound NacNacAl ( 1, NacNac = [ArNC(Me)CHC(Me)NAr] − and Ar = 2,6-Pr i 2 C 6 H 3 ) with fluoroarenes, fluoroalkanes, and ethers. Similar to the transition metals, the ease of aryl C–F oxidative addition decreases as the degree of fluorination diminishes on the aromatic substrate. As well, kinetic studies on the addition of 1,2,3,4-tetrafluorobenzene to compound 1 revealed a second-order reaction characterized by a very negative entropy of activation (Δ S ⧧ = −113.6(3) J/K·mol), consistent with a transition metal-like oxidative addition process.

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.
