Alkyne Hydroamination Inhibited by Vinylidene Deactivation
Bibliographic record
Abstract
Abstract The synthesis and isolation of [Ru(Cp)(P Cy 2 N Ph 2 )(=C=CHPh]PF 6 and [Ru(Cp*)(P Cy 2 N Cy 2 )(=C=CHPh)]PF 6 was successfully accomplished. Use of these ruthenium vinylidene complexes for stoichiometric reactions with a variety of amines was performed. Upon reaction with alkyl amines, deprotonation of the C β hydrogen resulted in formation of acetylide complex [Ru(Cp*)(P Cy 2 N Ph 2 )(−C≡CPh)], and the species was confirmed through independent synthesis. In contrast, reaction of the less basic aryl amine aniline with [Ru(Cp)(P Cy 2 N Cy 2 )(=C=CHPh)]PF 6 resulted in outer sphere addition to give a Fischer carbene product.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
