Physical Data: (1) bp 110 °C/0.2 mmHg. (2) mp 90–91 °C. (3) mp 114.5–116 °C. (4) bp 125–127 °C/5 mmHg. (5) bp 70 °C/0.1 mmHg. (8) bp 105 °C/0.6 mmHg. (7) bp 102 °C/2 mmHg. (8) bp 75–77 °C/0.2 mmHg. Preparative Methods: esters (5), (6), and (8) are available from commercial sources. The thioacetal acids may be prepared by thioacetalization of glyoxylic acid monohydrate3 or by reaction on the appropriate thiol(ate) with 2,2-dichloroacetic acid (or the diethyl acetal) directly4 or under phase transfer5 conditions using Aliquat 336. The esters may be obtained via similar exchange processes or via acid-catalyzed esterification of the corresponding acids.

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.
