Abstract

fetched live from OpenAlex

The reactivity of anionic metal-carbonyl systems toward hydrocarbons, alcohols and a variety of other classes of molecules is well established in the literature. In this study we explored the reactions of atomic metal anions M(-), notably K(-), Cs(-), Co(-), Fe(-), Cu(-) and Ag(-), with alcohols, alkanes, alkenes and alkynes. All of the metal anions deprotonated the alcohols and alkynes. Also observed were the subsequent reactions of the resulting organic anions. Fe(-) and Cu(-) consistently displayed mono- and bis-dehydrogenation of primary and secondary alcohols, and alkanes, alkenes and alkynes to form MH(-) and MH(2)(-). Mechanisms for the dehydrogenation reactions are proposed and substantiated with isotopically-labelled reagents and thermochemical arguments.

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.

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.
