Metal supported catalysts obtained by sol-gel in the hydrosilylation of phenylacetylene with R<sub>3</sub>SiH organosilanes (R<sub>3</sub> = Ph<sub>3</sub>, Ph<sub>2</sub>Me, and PhMe<sub>2</sub>)
Bibliographic record
Abstract
The hydrosilylation reaction of phenylacetylene, generated on the surface of solid catalysts (such as Pt and Ru) supported on inorganic matrices such as MgO obtained by the sol-gel process, yields vinylsilanes as the main products. The products' distribution, specific activity, and turnover reactions were determined for the case of the hydrosilylation reaction of PhC = CH with R 3 SiH (R = Ph 3 , Ph 2 Me, and PhMe 2 ). For Ph 3 SiH and Ph 2 MeSiH, the presence of β-trans and α isomers is observed. Addition of PhMe 2 SiH to phenylacetylene leads to the formation of β (cis and trans) and α isomers. These catalytic systems provide a new synthetic route to SiC bond formation.Key words: Vinylsilanes, sol-gel catalysts, hydrosilylation and phenylacetylene.

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; both teacher heads agree on what is shown here.
