Abstract
A novel synthetic pathway involving the desilylation of a tin trimethylsilyl species (Ph 2 Sn(SiMe 3 ) 2 ) towards nonprotected di(3-aminopropyl)tin dichloride ((H 2 N(CH 2 ) 3 ) 2 SnCl 2 ) is described. Di(3-aminopropyl)tin dichloride is then converted to the respective dicarboxylates species (H 2 N(CH 2 ) 3 ) 2 Sn(OCOR) 2 containing carboxylic acids of different lengths (R = –CH 3 , –(CH 2 ) 10 CH 3 ). Depending on the nature of R, discrete packing effects are observed in the solid state of di(3-aminopropyl)tin dicarboxylate derivatives. All the synthesized substances were characterized by 1 H, 13 C, and 119 Sn nuclear magnetic resonance data and also single crystal X-ray analysis. These compounds are a promising class of substances for biological, pharmaceutical, and technical applications.

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 it
