Reactions of Diorganomagnesium Compounds and Cryptands or 1,4,8,11-Tetramethyl-1,4,8,11-tetraazacyclotetradecane: Formation of RMg(macrocycle)<sup>+</sup> Cations and Organomagnesate Anions
Bibliographic record
Abstract
Many reactions of diorganomagnesium compounds (R 2 Mg) and a cryptand or 14N4 (1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) in benzene form solutions of RMg(macrocycle) + and organomagnesate ions. With 14N4 or 2,1,1-cryptand and 2 equiv of R 2 Mg, conversion to RMg(macrocycle) + and R 3 Mg - is complete. Conversion to RMg(macrocycle) + tends to be less complete with 2,2,1-cryptand and with some R 2 Mg compounds does not occur at all with 2,2,2-cryptand. Conversion to RMg(macrocycle) + tends to be greater when R is p -tolyl rather than alkyl and the solvent is benzene rather than THF. A crystal structure of PhMg(14N4) + Ph 3 Mg(THF) - is reported.

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.
