Cationic Low Oxidation State Phosphorus and Arsenic Compounds
Bibliographic record
Abstract
Compounds containing main group elements in unusually low oxidation states exhibit structural features and reactivities that are significantly different from those of analogous compounds containing the elements in their more typical oxidation states. This work summarizes the investigations of cationic univalent group 15 compounds, with a particular focus on the research derived from the seminal work of Schmidpeter concerning P(I) cations. These unusually stable "triphosphenium" cations consist of a P+ center stabilized by two phosphine donors and have the general form [R3P-P-PR3]+. Recently, interest in this type of compound has been re-kindled because of the unique modes of reactivity they may display. Improved synthetic strategies to such compounds, and their arsenic analogues, have been developed and current research exploits the unique chemistry of Pn(I) cations to produce unprecedented chemicals and materials.

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.
