Organotin (IV) Complexes as Catalyst for Biodiesel Formation: Synthesis, Structural Elucidation and Computational Studies

Here we have presented the synthesis of three novel triorganotin (IV) complexes: trimethylstannyl 4‐(3‐chloro‐2‐methylphenylamino)‐4‐oxobut‐2‐enoate ( 1 ); tributylstannyl 4‐(3‐chloro‐2‐methylphenylamino)‐4‐oxobut‐2‐enoate ( 2 ) and triphenylstannyl 4‐(3‐chloro‐2‐methylphenylamino)‐4‐oxobut‐2‐enoate ( 3 ). The ligand and its three complexes were spectroscopically characterized by NMR ( 1 H and 13 C) in solution and by FT‐IR in solid state....
