A series of novel amphiphilic ferrocenylimines and their cyclopalladated complexes of general formula [Fe(η5-C5H5)(η5-C5H4CR1{double bond, long}NR2)] (R1=H, R2=C12H25-n 4a, R1=H, R2=C16H33-n 4b, R1=CH3, R2=C12H25-n 4c, R1=CH3, R2=C16H33-n 4d), [PdCl{[(η5-C5H5)]Fe[(η5-C5H3)CR1{double bond, long}NR2]}]2 (5a-d), [PdCl{[(η5-C5H5)]Fe[(η5-C5H3)-CR1{double bond, long}NR2]}(PPh3)] (6a-d), were prepared and characterized by 1H NMR, 13C NMR, 31P NMR, IR, HRMS, and elemental analysis. The crystal structures of 5c,d were determined by X-ray crystallography. These amphiphilic cyclopalladated complexes are thermally stable and insensitive to oxygen and moisture. The redox properties of 4a-d, 5a-d, 6a-d were also investigated using cyclic voltammetric technique. Compounds 5a-d, 6a-d displayed good activity in the Heck reaction of a variety of aryl halides with ethyl acrylate or styrene and the Suzuki-Miyaura cross-coupling reaction of aryl bromides with phenylboronic acid in bulk solution. They are also suitable for formation of Langmuir-Blodgett (LB) films.
