Abstract

fetched live from OpenAlex

The reductive dehalogenation of a variety of vicinal-dibromide compounds has been accomplished through the use of α-sexithiophene as an organophotocatalyst. This photocatalytic system brings about the desired transformations in good yields, using low catalyst loadings and short reaction times. To help shed light on the efficiency of this process, we have studied the kinetics of the key mechanistic steps utilizing a combination of steady-state/time-resolved fluorescence and laser flash photolysis techniques.

Full frame distilled prediction

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.
