Abstract
A new living anionic ring-opening polymerization (ROP) method for sila[1]ferrocenophane 1 was developed using UV irradiation in the presence of Na[C5H5] as a promoter to afford controlled molecular weight polymers (Mn = 9.3 x 103 to 7.0 x 104, PDI = 1.04-1.21). A ring-opened ferrocenylsilane with a dangling silyl-substituted cyclopentadienyl anion, which was obtained from a near-stoichiometric photoreaction of 1 with Li[C5H4Me], indicates an Fe-Cp bond cleavage mechanism for the photolytic ROP.

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
