A Stable Homoleptic Divinyl Tetrelene Series
Bibliographic record
Abstract
Abstract The synthesis of the new bulky vinyllithium reagent ( Me IPr=CH)Li, ( Me IPr=[(MeCNDipp) 2 C]; Dipp=2,6‐ i Pr 2 C 6 H 3 ) is reported. This vinyllithium precursor was found to act as a general source of the anionic 2σ, 2π‐electron donor ligand [ Me IPr=CH] − . Furthermore, a high‐yielding route to the degradation‐resistant Si II precursor Me IPr⋅SiBr 2 is presented. The efficacy of ( Me IPr=CH)Li in synthesis was demonstrated by the generation of a complete inorganic divinyltetrelene series ( Me IPrCH) 2 E: (E=Si to Pb). ( Me IPrCH) 2 Si: represents the first two‐coordinate acyclic silylene not bound by heteroatom donors, with dual electrophilic and nucleophilic character at the Si II center noted. Cyclic voltammetry shows this electron‐rich silylene to be a potent reducing agent, rivalling the reducing power of the 19‐electron complex cobaltocene (Cp 2 Co).

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.
