Abstract
A 1:1 reaction of [HO(CH 2 ) 3 ] 3 P with 4-hydroxy-3-methoxy-cinnamaldehyde (coniferaldehyde) or 3,5-dimethoxy-4-hydroxycinnamaldehyde (sinapaldehyde) in acetone at room temperature affords phosphonium zwitterions of the type R 3 P + CH(4-O − -Ar)CH 2 CHO; other phosphines [R = Et, n -Bu, (CH 2 ) 2 CN, and p -Tol] do not react under the same conditions. In alcohols R’OH(D) [R’ = CD 3 , Et, (CD 3 ) 2 CD, s -Bu, HOCH 2 CH 2 ], the above phosphines (except the cyano-derivative) and those where R = i -Pr, Cy, Me 2 Ph, MePh 2 do react within an equilibrium established between the reactants and the zwitterion-hemiacetal products R 3 P + CH(4-O − -Ar)CH 2 CH(OH)(OR′) that are formed as a mixture of two diastereomers. The nature of the phosphine and the alcohol affects the equilibrium and the diastereomeric ratio.

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
