Portability of the RNNMo(3+) core Application to the synthesis of dinitrogen-derived trialkoxymolybdenum organodiazenido complexes
Bibliographic record
Abstract
An alcoholysis strategy has been employed in the synthesis of new oligo- or polymeric trialkoxymolybdenum diazenido complexes [R1NNMo(O-1-Ad)3]x (R1 = Me or C(O)OMe) as well as their mononuclear THF solvates R1NNMo(O-1-Ad)3(THF). Dinitrogen-derived diazenido precursor complexes R1NNMo(N[R]Ar)3 (R = i-Pr, Ar = 3,5-C6H3Me2) react smoothly with 3 equiv. 1-adamantanol to liberate 3 equiv. HN(R)Ar without disruption of the diazenidomolybdenum(3+) core. X-ray structural investigations were carried out for diazenido complex MeNNMo(O-1-Ad)3(THF) and for the corresponding cationic dimethyldiazenido complex [Me2NNMo(O-1-Ad)3(THF)]+, obtained as its triflate salt. The latter cation was found upon cobaltocene reduction to undergo NN bond cleavage, producing nitride NMo(O-1-Ad)3 (synthesized independently) and dimethylamine. Key words: molybdenum, dinitrogen, bond cleavage, hydrazido, diazenido.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
