Abstract

fetched live from OpenAlex

Abstract The utilization of photo‐induced processes in C−H functionalization via radical pathways has emerged as a highly promising strategy for the preparation and modification of complex organic compounds. While current methods for generating carbon‐centred radicals from C−H bonds primarily focus on hydridic C−H bonds to yield nucleophilic radical species, the reactivity and potential applications of electrophilic radicals derived from protic C−H bonds remain largely unexplored. In this review, we aim to shed light on the seminal findings regarding the activation of protic C(sp 3 )−H bonds while also showcasing noteworthy examples of this radical formation process. Mechanistically diverse modes of activation are discussed, unified by proton‐coupled electron transfer (PCET) concepts.

Teacher imitation

Not 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.
