Abstract
Tandem ROMP−hydrogenation enables efficient access to saturated, functionalized “ROMP polyolefins”. Of the Grubbs-class initiators 1 − 3, only third-generation catalyst 3 enables efficient ROMP of sterically demanding norbornenes with precise specification of chain lengths. Unlike 1 and 2, however, 3 decomposes rapidly during subsequent hydrogenation. By trapping the propagating species with PCy 3 immediately following ROMP, we generate a Ru-terminated chain identical to that formed from 2 and exhibiting equivalent hydrogenation activity. The remarkable ROMP efficiency of 3 can thus be integrated with the high hydrogenation activity of 2, providing efficient access to chain-length-precise, functionalized polyolefins.

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
