Bis(trimethylsilyl)methanesulfonyl and tris(trimethylsilyl)methanesulfonyl chlorides and their reactions by way of sulfenes
Bibliographic record
Abstract
Bis(trimethylsilyl)methanesulfonyl and tris(trimethylsilyl)methanesulfonyl chlorides (2c and 2d, respectively), have been prepared for the first time. Reactions of 2d with nucleophiles give products evidently derived from bis(trimethylsilyl)sulfene (1c). Reaction of 2c with piperidine gives the same piperidide as that from 2d, presumably via 1c formed by dehydrochlorination of 2c, whereas water and fluoride ion yield products consistent with their formation via trimethylsilylsulfene (1b) formed from 2c by attack at silicon with loss of the trimethylsilyl and chloro groups. No evidence for any enhanced stability in 1c was found.Key words: sulfonyl chlorides, sulfenes, silylsulfonyl chlorides, silylsulfenes, desilylation.

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.
