(<i>Z</i>)-2-Methylbuten-1-yl(aryl)iodonium trifluoromethanesulfonates containing electron-withdrawing groups on the aryl moiety
Bibliographic record
Abstract
The crystal structures of [(Z)-2-methylbut-1-en-1-yl][4-(trifluoromethyl)phenyl]iodonium trifluoromethanesulfonate, C(12)H(13)F(3)I(+).CF(3)O(3)S(-), (I), (3,5-dichlorophenyl)[(Z)-2-methylbut-1-en-1-yl]iodonium trifluoromethanesulfonate, C(11)H(12)Cl(2)I(+).CF(3)O(3)S(-), (II), and bis[[3,5-bis(trifluoromethyl)phenyl][(Z)-2-methylbut-1-en-1-yl]iodonium] bis(trifluoromethanesulfonate) dichloromethane solvate, 2C(13)H(12)F(6)I(+).2CF(3)O(3)S(-).CH(2)Cl(2), (III), are described. Neither simple acyclic beta,beta-dialkyl-substituted alkenyl(aryl)idonium salts nor a series containing electron-deficient aryl rings have been described prior to this work. Compounds (I)-(III) were found to have distorted square-planar geometries, with each I atom interacting with two trifluoromethanesulfonate counter-ions.

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.
