Heteroleptic iminopyrrolidinates of aluminium
Bibliographic record
Abstract
A series of iminopyrrolidine (ip) compounds were synthesized with excellent yields as potential ligands for novel organometallic precursors for atomic layer deposition. The idea behind these ligands was that carbodiimide (CDI) deinsertion would not occur as the quaternary carbon was tethered to one chelate nitrogen. To our advantage a melting point trend was evident within the ip ligands and reflected in the family of heteroleptic aluminium species when the ip ligands were reacted with TMA or TEA. The alkane elimination reaction occurred at room temperature yielding clean products with high yields. Crystal structures were collected for compounds 7 [ipipAlMe(2)], 12 [tbipAlMe(2)], and 14 [sbipAlEt(2)] demonstrating that the heteroleptic aluminium species were dimers. This was also evident in the mass spectra collected for each compound as the parent peak was that of the dimer minus a methyl. Thermolysis studies were carried out on all the ipAlMe(2) species to observe the decomposition at an isotherm over several days. The decay of the methyl peak was monitored as a ratio against TMS within the solution and was shown to be a first order decomposition. From these studies it was clear that nbip (9), iso-bip (10), and tbip (12) were the most stable complexes with half-lives of 24.8, 9.00, and 10.3 days, respectively.

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.
