The synthesis of complexes using precursor complexes with ferrocenyl carboxylate units as building blocks

We synthesized a mononuclear complex 1 and a binuclear complex 2 as precursor complexes. Investigation on the substitution reaction of two ferrocenyl carboxylate precursor complexes as building blocks, four complexes 1a, 1b, 2a and 2b were obtained. The structural integrity of precursor complexes can be maintained in these four complexes. It indicates that we can synthesize the desired complexes with the destination structures by using precursor complexes as building blocks and choosing appropriate auxiliary ligands.
