Abstract
Structurally diverse alcohols and phenols were trimethylsilylated in a clean and efficient reaction with hexamethyldisilazane (HMDS) based on the use of a catalytic amount of N-bromosuccinimide under both dichloromethane and solvent-free conditions at room temperature. Deprotection of trimethylsilyl ethers was also be achieved efficiently in the presence of a catalytic amount of NBS in methanol at ambient temperature.Key words: N-bromosuccinimide, solvent-free, alcohols, phenols, hexamethyldisilazane, trimethylsilyl ether, catalyst, detrimethylsilylation.

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
