Hydrido(methyl)carbene Complex of Platinum(IV)
Bibliographic record
Abstract
A hydrido(methyl)(carbene)platinum(IV) complex, using a stabilized Arduengo carbene, has been formed and characterized at low temperature by NMR. The electron-rich carbene complex [PtMe 2 {C 3 H 2 N 2 (CH 2 -2-py) 2 }] reacts with MeX (X = I or CF 3 SO 3 ) to give [PtMe 3 {C 3 H 2 N 2 (CH 2 -2-py) 2 }]X and is protonated at low temperature to give [PtHMe 2 {C 3 H 2 N 2 (CH 2 -2-py) 2 }]X, X = CF 3 SO 3, BF 4, or CF 3 CO 2 . At room temperature [PtHMe 2 {C 3 H 2 N 2 (CH 2 -2-py) 2 }] + undergoes irreversible reductive elimination of methane and dimerizes to give a binuclear bis{methyl(carbene)platinum(II)} complex cation [Pt 2 Me 2 {C 3 H 2 N 2 (CH 2 -2-py) 2 } 2 ] 2+ .

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.
