Reactivity and Electronic Properties of a Ferrocene Molecule Bearing an N,C-Chelated BMes<sub>2</sub> Unit
Bibliographic record
Abstract
A dimesitylboron-functionalized benzimidazolylferrocene, B(2-ferrocenyl- N -Me-benzimidazolyl)Mes 2 ( 1 ), has been synthesized and fully characterized. The B–N bond in 1 was found to undergo a dynamic dissociation/association process in solution, leading to a dynamic exchange of the two mesityls bound to the boron atom and slow hydrolysis of 1 under ambient conditions. The hydrolyzed product 2-BMes(OH)-1-( N -methylbenzimidazol-2-yl)ferrocene ( 2 ) was isolated and characterized, in which the boron center has a trigonal-planar geometry with one of the mesityls being replaced by an OH – group. The photoisomerization process of the boron unit in 1 was fully inhibited by the low lying d–d/MLCT states of the ferrocene unit. Compound 1 can be oxidized readily by I 2, forming the ferrocenium species [1 + ]I 3 - ( 3 ). NMR and EPR data for 3 indicated a notable spin delocalization through space from the Fe(III) center to a flanking mesityl group.

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.
