Synthesis and Reactivity of Novel Mesityl Boratabenzene Ligands and Their Coordination to Transition Metals
Bibliographic record
Abstract
The synthesis and characterization of novel bulky mesitylboratabenzene ligands have been achieved. The isolated boracyclohexadienes 6a, b were found to be extremely stable and could be selectively desilylated by hydrolysis. These ligands have been successfully coordinated to Fe(II) and Cr(II). The selective desilylation of the boratabenzene ring was also observed in the iron complexes, thus furnishing three ironboratabenzene sandwich complexes without a SiMe 3 group ( 11 ) and with one ( 10 ) and two ( 12 ) SiMe 3 groups. Interestingly, species 11 represents the first structurally characterized bis(boratabenzene) metallic species not exhibiting the expected trans geometry.

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.
