Abstract
Propargylic alcohols have been found to exhibit dual reactivity with bicyclic alkenes in the presence of Cp*Ru(cod)X (X =Cl, Br, I; Cp* = pentamethylcyclopentadienyl, cod = 1,4-cyclooctadiene). Cyclopropane and cyclobutene products can be obtained in a highly stereoselective fashion, but their formation is dependent on a variety of factors including the functional groups attached to the alkyne or alkene moieties and the nature of the ruthenium catalyst. To the best of our knowledge, this cyclopropanation proceeding through a β-hydride elimination or a [1,2]-hydride shift is an unprecedented catalytic pathway for ruthenium complexes.

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
