Triorganostannyl(IV) benzoates with pendulous framework appended with ferrocene scaffold

A series of four new long chain triorganotin(IV) esters containing a diazenyl- and an imino-groups appended with ferrocene scaffold were designed and synthesized. Ferrocene based metallo pro-ligands H'HFcL1 and H'HFcL2 were obtained by reacting isomeric 3-/4-ferrocenylanilines with 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1-diazenyl]benzoic acid, which upon reactions with appropriate triorganotin(IV) precursors yielded compounds namely,...
