Abstract
Abstract The trans ‐bis(trimethylsilyl)chalcogenolate palladium complexes, trans ‐[Pd( E SiMe 3 ) 2 (P n Bu 3 ) 2 ] [ E = S ( 1 ) and Se ( 2 )] were synthesized in good yields and high purity by reacting trans ‐[PdCl 2 (PBu 3 ) 2 ] with Li E SiMe 3 ( E = S, Se), respectively. These complexes were characterized by 1 H, 13 C{ 1 H}, 31 P{ 1 H} (and 77 Se{ 1 H}) NMR spectroscopy and single‐crystal X‐ray analysis. The reaction of 2 with propionyl chloride led to the formation of trans ‐[Pd(SeC(O)CH 2 CH 3 ) 2 (P n Bu 3 ) 2 ] ( 3 ), a trans ‐bis(selenocarboxylato) palladium complex and thus established a new method for the formation of this type of complex. Complex 3 was characterized by 1 H, 13 C{ 1 H}, 31 P{ 1 H} and 77 Se{ 1 H} NMR spectroscopy and a single‐crystal X‐ray structure analysis.

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
