Reaction of CO<sub>2</sub> with a Vanadium(II) Aryl Oxide: Synergistic Activation of CO<sub>2</sub>/Oxo Groups towards H‐Atom Radical Abstraction
Bibliographic record
Abstract
Abstract Treatment of divalent (ONNO)V(TMEDA) ( 1 ; ONNO=[2,4‐Me 2 ‐2‐(OH)C 6 H 2 CH 2 ] 2 N(CH 2 ) 2 NMe 2 ) with CO 2 afforded [(ONNO)V] 2 (μ‐OH)(μ‐formate) ( 2 ). Whereas the bridging hydroxo and formate groups both originated from CO 2 , the H atoms present on the two residues were obtained through H‐atom radical abstraction from the solvent. DFT calculations revealed an initially linear CO 2 bonding mode, followed by deoxygenation, and highlighted a synergistic effect between the so‐formed oxo group and an additional bridging CO 2 residue in promoting radical behavior.

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.
