Neutral and anionic zinc compounds supported by a bis(imino)phenyl NCN ligand
Bibliographic record
Abstract
The new zinc complexes 2,6-(ArN[double bond, length as m-dash]CH)2C6H3ZnBu (6) and 2,6-(ArN[double bond, length as m-dash]CH)2C6H3ZnCl2Li(THF)3 (7), supported by a bis(imino)phenyl NCN pincer ligand, were prepared (Ar = 2,6-iPr2C6H3). The reaction of complex 7 with LiHBEt3 resulted in a hydride transfer to the C[double bond, length as m-dash]N imine group to afford an unusual zinc dimer [η1(C),κ1(Nimine)-2-(ArN[double bond, length as m-dash]CH)-6-(Zn-N(Ar)CH2)C6H3Zn]2 (9). The latter transformation occurs via the formation of compound (η1(C),κ1(N)-2,6-(ArN[double bond, length as m-dash]CH)2C6H3)2Zn (8) which can also be accessed by the reduction of 7 with KC8.

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.
