This chapter contains sections titled: Introduction The DoM Reaction as a Methodological Tool The N-Cumyl Carboxamide, Sulfonamide, and O-Carbamate DMGs The Lithio Carboxylate and Carboxylate Ester DMGs The Di-tert-Butyl Phosphine Oxide DMG Heteroaromatic Directed ortho Metalation (HetDoM) in Methodological Practice π-Excessive Heteroaromatic Directed ortho Metalation (HetDoM) π-Deficient Heteroaromatic Directed ortho Metalation (HetDoM) The DoM–Transition Metal Catalyzed Aryl–Aryl Cross-Coupling Symbiosis The Suzuki–Miyaura–DoM Link Aryl O-Carbamate and S-Thiocarbamate–Grignard Cross-Coupling Reactions The DoM–Negishi Cross-Coupling Connection DoM–Derived Cross-Coupling Reactions. Synthetic Comparison of Boron, Zinc, and Magnesium Coupling Partners Beyond DoM: The Directed Remote Metalation (DreM) of Biaryl Amides and O-Carbamates – New Methodologies for Condensed Aromatics and Heteroaromatics Heteroatom-Bridged Biaryl DreM. General Anionic Friedel–Crafts Complements for Several Classes of Heterocycles Interfacing DoM with Emerging Synthetic Methods Closing Comments

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
