Controlled Specific Ligand Substitution and Chiroptical Properties of Ruthenium Bis(bipyridine) Nitrosoarene Complexes
Bibliographic record
Abstract
Abstract Reaction of rac-cis-Ru(Cl)2(bpy)2 with N,N-diethyl-4-nitrosoaniline (2) yields the compound rac-cis-[Ru(Cl)-(bpy)2(2)]Cl in 90–95% yield. Irradiation at 420 nm results in the novel specific substitution of the equatorial chloride ligand for MeCN, leaving the nitrosoarene ligand unaffected. X-ray analysis shows that the nitrosoarene ligand does not participate in an intramolecular π–π interaction with a bipyridine; molecular modelling confirms the relative instability of such a conformation. High thermal stability allows the Δ and Λ enantiomers to be separated and the circular dichroism spectra to be obtained; the anisotropy, or g, factors that are subsequently derived are found to be unexpectedly large.

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.
