Abstract

fetched live from OpenAlex

A unique family of N,N,π,C-palladacycles are synthesized from 8-aminoquinoline-coupled nopol derivatives through directed 1,2-migratory insertion of in situ generated arylpalladium(II) species followed by β-carbon elimination. These palladacycles have exceptional stability under air and moisture at room temperature, enabling successful isola-tion and characterization by X-ray crystallography, NMR, and high-resolution mass spectrometry. Computational studies shed light on the facile β-alkyl elimination step and the origins of the high stability of these post β-carbon-elimination complexes.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
