Selective Catalytic Frustrated Lewis Pair Hydrogenation of CO<sub>2</sub> in the Presence of Silylhalides
Bibliographic record
Abstract
Abstract The frustrated Lewis pair (FLP) derived from 2,6‐lutidine and B(C 6 F 5 ) 3 is shown to mediate the catalytic hydrogenation of CO 2 using H 2 as the reductant and a silylhalide as an oxophile. The nature of the products can be controlled with the judicious selection of the silylhalide and the solvent. In this fashion, this metal‐free catalysis affords avenues to the selective formation of the disilylacetal (R 3 SiOCH 2 OSiR 3 ), methoxysilane (R 3 SiOCH 3 ), methyliodide (CH 3 I) and methane (CH 4 ) under mild conditions. DFT studies illuminate the complexities of the mechanism and account for the observed selectivity.

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.
