Abstract
Fluorination at heterobenzylic positions can have a significant impact on basicity, lipophilicity, and metabolism of drug leads. As a consequence, the development of new methods to access heterobenzylic fluorides has particular relevance to medicinal chemistry. This short review provides a survey of common methods used to synthesize heterobenzylic fluorides and includes fluoride displacement reactions of previously functionalized molecules (e.g., deoxyfluorination and halide exchange) and electrophilic fluorination of resonance-stabilized heterobenzylic anions. In addition, recent advances in the direct fluorination of heterobenzylic C(sp3)–H bonds and monofluoromethylation of heterocyclic C(sp2)–H bonds are presented. 1 Introduction 2 Heterobenzylic Fluorides 2.1 Deoxyfluorination 2.2 Halide Exchange 2.3 Electrophilic Fluorination of Heterobenzylic Anions 2.4 Late Stage C–H Bond Fluorination 2.5 Monofluoromethylation of C(sp2)–H Bonds 3 Conclusions

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
