Abstract
The hydride compound DippNacNacZnH ( 1 ) catalyzes chemoselective hydrosilylation of ketones and aldehydes under mild conditions and chemoselective reduction of nitriles to imines. Mechanistic studies showed that the product of nitrile insertion into the Zn–H bond of 1, DippNacNacZn-N═C(H)(Ph) ( 2 ), is not a potent catalyst. Kinetic studies under catalytic conditions suggest a reversible coordination of silane to 1 to form an intermediate which then reacts with the substrate (nitrile or ketone) via a cyclic transition state to give the silylated product.

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
