Abstract
Ionic compounds containing phosphorus-based cations represent an important new direction in the fundamental chemistry of nonmetal elements.In this work, we explored the reactivity of phosphino-phosphonium cations with sulfur and selenium, with a view towards new synthetic methods for phosphorus-chalcogen cations. We present several new cations which have been identified by 31P NMR spectroscopy and single crystal x-ray diffraction, that are analogous to the recently reported chalcogenides of phosphanylboranes. We also present new diphosphonium-diselenide cations which have been formed through a unique redox equilibrium of triphenylantimony(V) bistriflate and trialkylphosphineselenides on one side and the diphosphonium diselenide cations and triphenylantimony(III) on the other side.

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 it
