Bibliographic record
Abstract
Abstract Two new chalcogen-nitrogen heterocycles, tBuNSe(μ-NtBu)2SO2 (1) and tBuNSe(μ-NtBu)2SeO (2), have been prepared by the reaction between tBuNH2, SeCl4, and SO2Cl2 or SeOCl2. tBuNSe(μ-NtBu)2SeO can also be generated by cycloaddition reaction of tBuNSeNtBu with tBuNSeO. Both (1) and (2) contain a slightly puckered four-membered E2N2ring, containing nitrogen chalcogen single bonds. The length of the exocyclic nitrogen-selenium bond in both molecules indicates a double bond. Products have been identified and characterized by using X-ray diffraction, NMR spectroscopy and elemental analysis. Keywords:: Chalcogen-nitrogen-compoundsNMR spectroscopycrystal structure

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.
