On the Barton Copper‐Catalyzed C3‐Arylation of Indoles using Triarylbismuth bis(trifluoroacetate) Reagents
Bibliographic record
Abstract
Invited for this month's cover are the collaborating groups of Prof. Alexandre Gagnon at the Université du Québec à Montréal in Canada, and Dr. Claire McMullin at the University of Bath in the UK. The cover picture represents the "Chasse-galerie", a popular French-Canadian tale published by the author Honoré Beaugrand in 1892, adapted with landmarks from Montréal, London, and Bath. The aryl groups are being transferred from a pentavalent triarylbismuth reagent to the C3 position of an indole via a copper-catalyzed C-H activation mechanism. Cover designed by Lysanne Arseneau. More information can be found in the Research Article by Claire L. McMullin, Alexandre Gagnon, and co-workers.
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 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.
