A novel liquid-phase strategy for organic synthesis using organic ions as soluble supports
Bibliographic record
Abstract
This critical review describes a new liquid-phase strategy for organic synthesis by using organic ions as soluble supports. Catalysts or reagents or substrates are immobilized onto organic ions. They are generally soluble in polar organic solvents (e.g. CH(3)CN) or ionic liquids but insoluble in non-polar solvents (e.g. ether or hexanes). Their reactions are carried out in homogeneous solution phase with a polar organic solvent or ionic liquid. After the reaction, the ion-supported species can be phase separated through precipitation from the polar organic solvent by the addition of a less polar organic solvent or extraction with organic solvents from ionic liquids. The ion-supported species can therefore be easily recovered and purified from the reaction mixture by simple washings with the less polar solvent. The ion-tagged species can function in the role of a catalyst, or as a reagent, or as the substrate in the synthesis of small molecules or bio-oligomers. Ion-supported catalysts and reagents can usually be recovered and reused with little diminution of activity. Important biooligomers such as peptides, oligosaccharides and oligonucleotides have been synthesized with this method (136 references).

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.
