Abstract

fetched live from OpenAlex

Abstract Theoretical studies were conducted on the predicted gas and solution phase thermodynamic properties for isomerization of various [1.1]paracyclophane derivatives to their corresponding transannular[4+4] adducts at representative levels of density functional and composite method theory. Calculations suggest the [1.1]paracyclophane to transannular[4+4] adduct isomerizations are not likely amenable to thermodynamic solvent tuning for the methylene, ether, and thioether bridged derivatives using a broad range of nonpolar and polar aprotic and polar protic implicit solvation models, but may be receptive towards solvent tuning for the amine bridged analogs. Varying the nature of the cyclophanic bridging atoms and the electron withdrawing/releasing character of photochemically/thermally stable substituents on the [pi]-systems is predicted to facilitate substantial variation of the isomerization equilibria to a much greater degree than changing the solvent environment.

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.
