Abstract
Diorganotin(IV) complexes of flexible N-protected amino acids and ketoximes having the compositions Me 2 Sn [[Formula: see text]CHRCOO][ON = C 6 H 10 ] (where R = –CH 2 CH(CH 3 ) 2 , –CH(CH 3 )C 2 H 5 ,–CH 2 C 6 H 5 , –CH(CH 3 ) 2 ) and Me 2 Sn[[Formula: see text]CHRCOO][ON=CR′R″] (where R = –CH 2 CH(CH 3 ) 2 , –CH(CH 3 )C 2 H 5 , –CH 2 C 6 H 5 , R′ = R″ = CH 3 ; R = –CH(CH 3 )C 2 H 5 , –CH 2 C 6 H 5 , –CH(CH 3 ) 2 , R′ = CH 3 , R″ = C 6 H 5 ) were prepared by the reaction of dimethyltin(IV) dichloride with sodium salts of flexible N-protected amino acids and ketoximes in 1:1:1 molar ratio in refluxing dry benzene. The synthesized complexes were characterized by elemental analyses and IR, multinuclear NMR ( 1 H, 13 C, and 119 Sn), and mass spectral studies. Plausible structures of these complexes have been suggested on the basis of molecular weight measurements and spectral data. 119 Sn NMR spectral data indicate the presence of pentacoordinated tin centres in these complexes. Some of the synthesized complexes and their ligands were also screened for their in vitro antimicrobial activity.

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
