Abstract
Two isomeric Pt(II) complexes, Pt(L1)(CH 3 ) 2 ( 1a ) and Pt(L2)(CH 3 ) 2 ( 2a ), based on two isomeric and fluorescent ligands of bis( N- 7-azaindolyl)methane, L1 (symmetric) and L2 (asymmetric), have been synthesized and fully characterized by NMR and X-ray diffraction analyses. In the presence of [H(Et 2 O) 2 ][BAr‘ 4 ] (Ar‘ = 3,5-bis(trifluoromethyl)phenyl), both 1a and 2a are capable of activating a benzene C−H bond readily at ambient temperature. The products from benzene activation by 1a and 2a have been isolated as [Pt(L1)Ph(SMe 2 )][BAr‘ 4 ] ( 1b ) and [Pt(L2)Ph(SMe 2 )][BAr‘ 4 ] ( 2b ). The structures of 1b and 2b have been determined by X-ray diffraction analyses. The phenyl ligand in 2b is bound exclusively trans to the pyrrole nitrogen atom of L2 .

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
