Bibliographic record
Abstract
Abstract [2‐(Me 2 NCH 2 )C 6 H 4 ]SeS(S)PR 2 [R = Ph (1), O i Pr (2)] were prepared by reacting [2‐(Me 2 NCH 2 )C 6 H 4 ] 2 Se 2 with the appropriate disulfanes, [R 2 P(S)S] 2 . The compounds were characterized by multinuclear magnetic resonance ( 1 H, 13 C, 31 P). The molecular structures of 1 and 2 were determined by single‐crystal X‐ray diffraction. Both compounds are monomeric and the nitrogen atom of the pendent CH 2 NMe 2 arm is strongly coordinated to the selenium atom. The organophosphorus ligands are monodentate, thus resulting in a T‐shaped coordination geometry around selenium. Copyright © 2002 John Wiley & Sons, Ltd.

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; both teacher heads agree on what is shown here.
