Abstract
Abstract I 2 /DABCO (iodine/1,4‐diazabicyclo[2.2.2]octane)‐mediated oxidative coupling of nitrosobenzenes with aromatic amines was revealed to lead to the production of unsymmetrical aromatic azoxy compounds, instead of azo compounds reported previously in Mills reaction. Our study illustrates that various aromatic amines can be efficiently coupled with nitrosobenzenes to produce unsymmetrical azoxy product, in which more than thirty unsymmetrical azoxybenzenes have been successfully prepared. The applicability to a broad range of substrates, scalability to large scales and mild reaction conditions make this new synthetic protocol very practical, providing a convenient and direct access to unsymmetrical azoxybenzenes. magnified image

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 it
