(S,R,Rp)-N,N-Dimethyl-1-{2-[(1-phenylethyl)aminomethyl]ferrocenyl}ethanamine

Abstract

The title chiral ferrocene compound, [Fe(C5H5)(C18H25N2)], contains one planar and two central chiral centers. It is of interest with respect to asymmetric catalysis. The absolute configuration of the planar chirality is Rp at the ferrocene group and those of the two C chiral centers are R at the CH carbon of the ethanamine unit and S at the CH carbon of the phenylethylamino substituent. In the ferrocenyl unit, the cyclopentadienyl (Cp) rings are planar, with maximum deviations of 0.002 (2) Å for the substituted and 0.008 (3) Å for the unsubstituted Cp ring. The dihedral angle between the ring planes is 2.12 (15)° and the rings are twisted slightly from an eclipsed conformation by 7.06–7.60°.
