Synthesis and Crystal Structures of Ferrocenylamine Alcohols of Ferrocenylformaldehyde with Aminoalcohols

Two chiral ferrocenylamine alcohols of (R)-[Fe(η⁵-C₅H₅){η⁵-C₅H₄CH₂NHCH(ⁱPr)(CH₂OH)}] (1) and (R)-[Fe(η⁵-C₅H₅){η⁵-C₅H₄CH₂NHCH(C₆H₅)(CH₂OH)}] (2) were synthesized by condensation reaction of ferrocenylformaldehyde and chiral aminoalcohols followed by the reduction with sodium borohydride. The crystal structures of the two compounds were determined by single crystal X-ray diffraction. Compound 1 crystallizes in the orthorhombic space group P2₁2₁2 with a = 16.600(8) Å, b = 28.990(14) Å, c = 6.531(3) Å, and Z = 8. Compound 21.13H₂O crystallizes in the monoclinic space group I2 with a = 22.671(4) Å, b = 6.2481(10) Å, c = 22.112(4) Å, β = 96.763(12)°, and Z = 8.
