{[(N-Methyl-N-p-R-benzyl)amino]benzyl}ferrocenes 4a–c (R = H(a), OCH3(b), CH3(c)) were synthesized by N-methylation of the corresponding sec-amines 3a–cwith the reagent CH3I-t-BuOK. Treatment of 4a–c with Na2PdCl4 in the presence of NaOAc produced a pair of palladacycles σ-Pd[(η5-C5H5)Fe(η5- C5H3CH(C6H5)N(CH3)CH2-C6H4-R)]Cl(PPh3) 5a–c (R = same as before) consisting of RNRP and SNSP configurations. The structure of 5a was determined by single crystal X-ray analysis. High catalytic activities of 5a–c for the Suzuki coupling of aryl chlorides with phenylboronic acid and the Heck reaction of bromobenzene with styrene were observed.
