Sequential Insertion of Carbon Monoxide and Imines into Nickel−Methyl Bonds: A New Route to Imine Hydroacylation
Bibliographic record
Abstract
The sequential insertion of carbon monoxide and imines has been achieved at ambient temperatures with cationic nickel complexes, yielding the nickel-chelated amides (bipy)Ni[η 2 -C(H)TolN(R)COCH 3 ] + X - (bipy = 2,2‘-bipyridyl; Tol = p -tolyl; R = alkyl, aryl; X = OTf, PF 6, SbF 6, B(3,5-C 6 H 3 (CF 3 ) 2 ) 4 ). The addition of KCN/methanol to these products of CO/imine insertion leads to cleavage of the amide ligand, providing a facile method to achieve the overall hydroacylation of imines under mild conditions.

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.
