Abstract

fetched live from OpenAlex

Abstract A rationale for the unusually strong Lewis basicity and catalytic activity of the title pro-azaphosphatranes is presented. Four stoichiometric and four catalytic uses of such pro-azaphosphatranes are described, as well as some unexpected reactions in which these bases take part. Mechanistic pathways are put forth for several of the transformations outlined. Keywords: BasesCarbon-fluorine ActivationCatalystsPro-azaphosphatranesTransannulation

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.
