Cu(i)/(ii) based catalytic ionic liquids, their metallo-laminate solid state structures and catalytic activities in oxidative methanol carbonylation
Bibliographic record
Abstract
Three types of copper-containing catalytic ionic liquids (CILs) have been synthesised and fully characterised by spectroscopy, elemental, thermal and, in most cases, XRD analyses. Whereas type I ILs comprise copper exclusively in the cation (e.g. [Cu(Im12)4][PF6], Im12 = 1-dodecylimidazole), type II ionic liquids contain Cu(I) in both the cation and the anion (e.g. [Cu(Im12)2][CuBr2]) and type III ILs incorporate copper solely in form of halocuprate(I)/(II) anions (e.g. [DMIM][CuBr2], DMIM = 1-dodecyl-3-methylimidazolium). A limitation concerning the preparation of a series of type II ionic liquids has been observed by the formation of the neutral compound [Cu(Im12)I]6 instead of the expected IL [Cu(Im12)2][CuI2]. The novel ILs reveal a metallo-laminate structure in the crystalline state. The salts have a liquidus range of up to 300 °C before decomposition takes place. Their catalytic properties in the synthesis of dimethyl carbonate from MeOH, CO and O2 have been studied.

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.
