Photoinitiated <i>anti</i>‐Hydropentafluorosulfanylation of Terminal Alkynes
Bibliographic record
Abstract
Abstract A photoinitiated anti ‐hydropentafluorosulfanylation of terminal alkynes using SF 5 Cl and (TMS) 3 SiH as the hydrogen atom donor is reported. This transformation generates selectively ( Z )‐(1‐alken‐1‐yl)pentafluoro‐λ 6 ‐sulfanes ( Z : E : >85:15), thus allowing the preparation of this previously unknown geometrical isomer. DFT calculations highlight that the selectivity is due to the intrinsic preference of SF 5 ‐substituted vinylic radicals to adopt a cis geometry, and to increased steric contacts during the transition structures leading to the minor ( E )‐products.

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.
