Synthesis, characterization and thermal analysis of organotin (IV) derivatives of 4- (N-maleoyl) butanoate

Organotin(IV) derivatives of the type $R_{4-n}SnLn$ where R = Me, n-Bu, Ph, L = 4 - (N-maleoyl)butanoate and n = 1 or 2 were synthesized by refluxing $R_3SnCl$ and $R_2SnCl_2$ with (4-(N-maleoyl)butanoate in the presence of triethylamine using dry toluene as solvent. These compounds were characterized by IR, multinuclear NMR and mass spectrometry. We also studied their thermal behavior and calculated the degradation pattern, ener activation ($E_a$) and order of reaction (n).
