Abstract

fetched live from OpenAlex

Olefin metathesis catalysts containing chelating aryloxide donors, RuXX‘(IMes)(py)( CHPh) ( 5, XX‘ = 3,5-dichloro-2-oxidobenzenesulfonate; 6, XX‘ = catecholate), are accessible in high yield by reaction of o -sulfonato aryloxide or catecholate salts, respectively, with RuCl 2 (IMes)(py) 2 ( CHPh). Isomerization to π-bound aryloxides, as found with phenoxide ion or 2‘-(diphenylphosphino)-1,1‘-binaphthyl-2-olate, is suppressed by use of these smaller, more rigid, chelate rings. Preliminary investigations indicate that the catecholato derivative exhibits metathesis activity approaching that of the recently reported, highly active catalyst RuCl(OC 6 Br 5 )(IMes)(py)( CHPh).

Full frame distilled prediction

Teacher imitation

Not 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.
