Abstract
The new monohydride RuHCl(PPh 3 ) 2 ( R, R -cydn), with base added, and dihydride RuH 2 (PPh 3 ) 2 ( R, R -cydn), in the absence of base, catalyze the hydrogenation of a wide variety of ketones and some imines at 3 atm of H 2 and 20 °C with high turnover numbers. The mechanism is thought to involve the concerted dihydrogen transfer from cis hydride and N−H groups to the substrate followed by heterolytic dihydrogen splitting.

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
