Transformations of Aryl Isocyanide on Guanidinate-Supported Organozirconium Complexes To Yield Terminal Imido, Iminoacyl, and Enediamido Ligands
Bibliographic record
Abstract
Reactions of aryl isocyanide with bis(guanidinate) Zr(IV) hydrocarbyl complexes are presented. With 1 equiv of Ar‘NC the ultimate products are the terminal Zr imido complexes [{(R‘NR‘ ‘)C(NR) 2 } 2 ZrN(2,6-Me 2 C 6 H 3 )] ( 3, R = R‘ = i Pr, R‘ ‘ = H; 5, R = i Pr, R‘ = R‘ ‘ = Me), which are derived via a unique transformation from intermediate η 2 -iminoacyl species. With 2 equiv of Ar‘NC, [{(Me 2 N)C(N i Pr) 2 } 2 Zr(η 2 -Ar‘N CMe) 2 ] ( 6 ) was isolated. Mild thermolysis of 6 generates an enediamido complex via intramolecular coupling of the iminoacyl groups.

How this classification was reachedexpand
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.
