π-Delocalization in the vicinal lone pairs of hydrazines: Structure and electronic effects in derivatives of 9-aminocarbazole
Bibliographic record
Abstract
A series of four substituted carbazoles with N-N bonds have been prepared, characterized, and structurally determined by single crystal X-ray diffraction. These include derivatives with donating amino, NNH 2 , electron withdrawing mono-and bisacetyl, NNHC(O)Me and NN[C(O)Me] 2 , and conjugating Shiff base derivatives from the condensation of 9-aminocarbazole with arylaldehydes. The electronic structure and optimized gas phase structures of all four have been determined with density functional theory, B3LYP, and triple zeta basis sets either 6-311++g** or cc-pvtz. Together these experimental and theoretical results allow for the contrast of all four predominant N-N bonds in hydrazine derivatives.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
