Synthesis, structural characterization and electrochemistry of C,N-chelated organotin(IV) dicarboxylates with ferrocenyl substituents

Abstract

A set of C,N-chelated organotin(IV) ferrocenecarboxylates, [L(CN)(n-Bu)Sn(O(2)CFc)(2)] (1), [(L(CN))(2)Sn(O(2)CFc)(2)] (2), [L(CN)(n-Bu)Sn(O(2)CCH(2)Fc)(2)] (3), [L(CN)(n-Bu)Sn(O(2)CCH(2)CH(2)Fc)(2)] (4), [L(CN)(n-Bu)Sn(O(2)CCH=CHFc)(2)] (5), [L(CN)(n-Bu)Sn(O(2)CfcPPh(2))(2)] (6), [(L(CN))(2)Sn(O(2)CfcPPh(2))(2)] (7), and [L(CN)(n-Bu)(2)Sn(O(2)CFc)] (8) (L(CN) = 2-(N, N-dimethylaminomethyl)phenyl, Fc = ferrocenyl and fc = ferrocene-1,1'-diyl) has been synthesized by metathesis of the respective organotin(IV) halides and carboxylate potassium salts and characterized by multinuclear NMR and IR spectroscopy, X-ray diffraction and electrochemical methods.
