In Situ Synthesis of Cu-CP by Cleavage of the C–N Bond for CO <sub>2</sub> Fixation into Oxazolidinones through Aziridine/Propargylamine under Ambient Conditions
Bibliographic record
Abstract
The conversion of CO 2 into high-value chemicals under mild conditions offers the advantages of atom economy, bond-formation efficiency, and product complexity. Among the transformations, coupling reactions of CO 2 with arizidine/propargylamine to produce oxazolidinones represent an important and attractive method to utilize CO 2 . Herein, we report two Cu-CP catalysts ( Cu-CP-1 and Cu-CP-2 ) through flexible imidazole-containing ligands for the synthesis of oxazolidinones from aziridines/propargylamine and CO 2 under ambient conditions (room temperature, 1 atm of CO 2 ). Notably, Cu-CP-1, prepared via a C–N cleavage reductive strategy, exhibits a significantly higher catalytic activity. The planar four-coordinated Cu centers play an important role in the catalysis.

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.
