Abstract
Abstract The use of iron catalysis to enable reactions with diazo compounds has emerged as a valuable tool to forge carbon–carbon or carbon–heteroatom bonds. While diazo compounds are often encountered with toxic and expensive metal catalysts, such as Rh, Ru, Pd, Ir, and Cu, a resurgence of Fe catalysis has been observed. This short review will showcase and highlight the recent advances in iron-mediated reactions of diazo compounds. 1 Introduction 2 Insertion Reactions 2.1 Insertion into B–H Bonds 2.2 Insertion into Si–H Bonds 2.3 Insertion into N–H Bonds 2.4 Insertion into S–H bonds 3 Ylide Formation and Subsequent Reactions 3.1 Doyle–Kirmse Rearrangement 3.2 [1,2]-Stevens and Sommelet–Hauser Rearrangements 3.3 Olefination Reactions 3.4 Cycloaddition Reactions 3.5 gem-Difluoroalkenylation 4 Three-Component Reactions 5 Miscellaneous 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
