Abstract
The transfer-hydrogenation of ketones with iPrOH in the presence of a base is catalyzed by pincer-aryl ruthenium(II) complexes (see scheme, R3=NMe2 or PPh2, X=Cl or OSO2CF3). Conversions of 90 – 98 % are achieved without removal of the acetone by-product. The structural unit [Ru(pincer-aryl)PPh3] is stable under the reaction conditions and is preserved during the catalytic cycle. An anionic Ruii hydrido complex was identified as the resting state of the catalyst at the onset of the reaction.

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
