Abstract
The synthesis of titanium cyclopentenediolates by the double carbonylation of titanacyclobutane complexes is reported, a process known as the Bercaw carbonylation. The reaction is general for a range of titanacyclobutanes prepared by free radical alkylation of allyltitanium(III) precursors. Titanacyclobutane formation and carbonylation can be conducted in one pot without the isolation of sensitive intermediates. Subsequent conversion to lithium cyclopentenediolates and cyclopentane-1,2-diones provides access to a range of synthetically valuable organic products.

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
