MCl<sub><i>x</i></sub> (M = Hg, Au, Ru; <i>x</i> = 2, 3) catalyzed hydrochlorination of acetylene — A density functional theory study
Bibliographic record
Abstract
Density functional theory (DFT) calculations were used to study the mechanism for the hydrochlorination of acetylene catalyzed by MCl x (M = Hg, Au, Ru; x = 2, 3). For the three catalysts, the reaction occurs via a one-shift chlorine atom transfer, which avoids the formation of highly stable complex species. The adsorbed HCl acts as a chlorine donor, while the C 2 H 2 favors the chlorine abstraction. The calculated real activation barrier decreases in the order: HgCl 2 > AuCl 3 > RuCl 3 , which suggests that the RuCl 3 would be a good candidate catalyst for the hydrochlorination of acetylene.

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.
