Abstract

fetched live from OpenAlex

Ortsfest: Eine Reihe neuer Pd-Komplexe mit N-heterocyclischen Carbenliganden wurde in der Negishi-Kreuzkupplung von Aryl- und Heteroarylchloriden, -bromiden und -triflaten mit vielfältigen sekundären Alkylzinkreagentien getestet (siehe Schema). Es entsteht nahezu ausschließlich das Produkt der direkten Eliminierung, und in den meisten Fällen tritt keinerlei migratorische Insertion auf. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer-reviewed, but not copy-edited or typeset. They are made available as submitted by the authors. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors. Any queries (other than missing content) should be directed to the corresponding author for the article.

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.
