Synthesis, characterization of cyclopalladated ferrocenylamines possessing both central and planar chirality: The crystal structure of (RC,RN,RP)-σ-Pd[(η5- C5H5)Fe(η5-C5H3CH2N(CH3)CHCH3C6H5)]Cl(PPh3) · 1/2H2O

Condensation of ferrocenylcarboxaldehyde and (R),(S)-α-methylbenzylamines resulted in ferrocenylaldimines 1a, 1b, respectively. Reduction of 1a(b) with lithium aluminum hydride in THF afforded the sec-ferrocenylamines 2a(b). N-Methylation of 2a(b) with sodium cyanoborohydride, formaldehyde and acetic acid yielded the tert-ferrocenylamines 3a(b). Cyclopalladation of 3a(b) with disodium tetrachloropalladate in the presence of sodium acetate produced 4a, b with the absolute configurations RCRNRP and SCSNSP, respectively. The structure of 4a was determined by X-ray single crystal analysis.
