Halide anions are formed from reactions between atomic metal anions and halogenated aromatic molecules
Bibliographic record
Abstract
Atomic metal anions (AMAs) Fe – , Cs – , Cu – and Ag – were generated in the gas phase by collisionally decomposing the corresponding metal‐oxalate anion. Mass selected AMAs were allowed to react with halogenated and nitrated molecules (C6H5Cl, C6H4Cl2, C6H3Cl3, C6H5I, C6H5Br and C6H5NO2) in the collision hexapole of a triple‐quadrupole mass spectrometer. Observed reactions include the predominant formation of X – (X = Cl, Br and I), as well as FeCl – , FeCl2 – and FeCl3 – when Fe‐ reacted with the mono, di and tri‐chlorobenzenes; reactions between 1,4‐dichlorobenzene and Cs – produced Cl – , CsCl – and CsCl2 – ; reactions involving iodobenzene also produced, CsI – , CsI2 – and AgI – . The results suggest that the reaction to form X – (X = Cl, Br, I and NO2) may be a promising route to improving the detection efficiency by mass spectrometry for such analytes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
