Abstract

fetched live from OpenAlex

Abstract By careful choice of reaction conditions 1‐methylnaphtho[1,8‐ de ]‐1,2,3‐triazine and 1,3‐dimethylnaphtho[1,8‐ de ]‐1,2,3‐triazinium triflate are readily prepared by the alkylation of 1 H ‐naphtho[1,8‐ de ]‐1,2,3‐triazine. The electronic spectra for these bathochromically shifted dyes are reported for a range of solvents as are their vibrational spectra and theoretical structures from density functional theory, B3LYP/6‐311++G**. The 15 N substitution into the middle nitrogen atom allows for the identification of strong azine bands in the IR and Raman spectra as well as in the 15 N NMR spectrum. X‐ray crystallography is used to characterize the solid‐state structures of two of these new triazine derivatives and these structures are used to benchmark the theoretical and spectroscopic discussions. The corresponding 1,3‐dimethyltriazinium radical is prepared and characterized by cyclic voltammetry, spectroelectrochemistry, and EPR spectroscopy. Unlike the related transient 1,2,4‐triazene radicals, the 1,3‐dimethyl‐1,2,3‐naphthotriazyl radical is markedly more stable.

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.
