(PNSiMe <sub>3</sub> ) <sub>4</sub> (NMe) <sub>6</sub> : A Robust Tetravalent Phosphaza‐adamantane Scaffold for Molecular and Macromolecular Construction**
Bibliographic record
Abstract
Abstract Tetraarylmethanes and adamantanes are important rigid covalent connectors that play a four‐way scaffolding role in molecular and materials chemistry. We report the synthesis of a new tetravalent phosphaza‐adamantane cage, (PNSiMe 3 ) 4 (NMe) 6 ( 2 ), that shows high thermal, air, and redox stability due to its geometry. It nevertheless participates in covalent four‐fold functionalization reactions along its periphery. The combination of a robust core and reactive corona makes 2 a convenient inorganic scaffold upon which tetrahedral molecular and macromolecular chemistry can be constructed. This potential is demonstrated by the synthesis of a tetrakis(bis(phosphine)iminium) ion (in compound 3 ) and the first all P/N poly(phosphazene) network ( 5 ).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
