Abstract

fetched live from OpenAlex

[Chemical reaction: See text] A practical three-step synthesis of bis(pyrrol-2-yl)arylenes has been accomplished, featuring a copper-catalyzed tandem bidirectional addition of vinylmagnesium bromide to aryldicarboxylates. Spectroscopic and cyclic voltammetric analyses revealed the influence of the central aromatic core and pyrrole substitution pattern on the electrochemical properties of these comonomers.

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.
