Abstract
The mild, room-temperature oxidation of a primary alcohol catalyzed by tetrapropylammonium perruthenate (TPAP) is presented for the undergraduate organic laboratory. In this experiment, geraniol is oxidized to form geranial, a liquid product that is easily characterized via IR and proton NMR spectroscopy. Both substrate and product have very distinct and pleasant odours, so their respective reactivity and formation generates class interest. Comparison between this synthesis and other alcohol oxidation procedures affords discussion of catalytic behaviour apparent in the former method. Although catalysis is favourable in terms of green chemistry, certain improvements can be made from a sustainability perspective, which is an important focal point for student discourse. The reaction also provides an opportunity to perform a reaction under dry conditions, and to investigate a detailed autocatalytic mechanism of TPAP oxidation.

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 it
