Abstract
Abstract The activation of C–C bonds via transition metal catalysis has become an increasingly popular strategy in organic synthesis. An emerging method to cleave C–C bonds is to facilitate a β-carbon elimination using rhodium or palladium catalysis. This elementary step typically relies on a thermodynamic driving force, such as the relief of ring strain or steric strain. More recently, the use of neopentyl metal species or chelation assistance has enabled this difficult transformation. This review will cover recent synthetic applications of β-carbon eliminations under palladium and rhodium catalysis. 1 Introduction 2 Chelation-Assisted β-Carbon Elimination Reactions 3 β-Carbon Elimination from Neopentyl–Pd Species 4 Pd-Catalyzed Catellani Reactions 5 β-Carbon Elimination Reactions of Cyclopropanes 6 Conclusion

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
