Synthese und Metallomimetische Reaktivität eines Transienten, Zweifach Koordinierten Alkylborylens
Bibliographic record
Abstract
Kurzzusammenfassung Während sich die bisherige Literatur hauptsächlich auf carbenstabilisierte Amino‐ und Arylborylene der Form [(Carben)BR] (R = Substituent) konzentriert hat, berichten wir hier über die Synthese und metallomimetische Reaktivität des ersten carbenstabilisierten Alkylborylens [(CAAC Me )BCy] (CAAC Me = 1‐(2,6‐Di iso propylphenyl)‐3,3,5,5‐tetramethylpyrrolidin‐2‐yliden, Cy = Cyclohexyl). Darüber hinaus werden die übergangsmetallähnlichen Decarbonylierungsreaktionen eines Borylenkomplexes, [(CAAC Me )BCy(CO)], der sich aus dem Borylen [(CAAC Me )BCy] und CO ableitet, beschrieben. Zu den zusätzlichen Erkenntnissen gehören (i) die Identifizierung der verschiedenen Stufen, auf denen der Ligand (L) unter Bildung der Komplexe [(CAAC Me )BCyL] bei der Reduktionsroute ausgehend vom Edukt [(CAAC Me )BCyBr 2 ] und bei der Photolyse des Carbonylkomplexes [(CAAC Me )BCy(CO)] ans Boratom binden kann, und (ii) Erkenntnisse aus quantenchemischen Berechnungen bezüglich der molekularen und elektronischen Struktur des Borylens in den verschiedenen Stadien.

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.
