Bildung und Kristallstruktur von FcCH(t‐Bu)NHCH(Me)CH2OMe · LiI · Et2O

Formation and Crystal Structure of FcCH( t ‐Bu)NHCH(Me)CH₂OMe · LiI · Et₂O The title compound FcCH(t‐Bu)NHCH(Me)CH₂OMe · LiI · Et₂O ( 1 · LiI · Et₂O) was obtained by reaction of FcCH(t‐Bu)N(Li)CH(Me)CH₂OMe with MeI in a molar ratio 1 : 1 in diethylether. The Li atom is substituted by an H atom yielding the secondary amine. The formation of the expected N‐methyl substituted species could not be observed. 1 creates monomeric molecules with four coordinate Li atoms as a result of Li–N and Li–O interactions of the corresponding atoms of the ferrocenyl ligand and a solvent molecule. 1 · LiI · Et₂O: Space group P2₁2₁2₁, Z = 4, lattice dimensions at –60 °C: a = 10.492(2), b = 13.225(2), c = 18.846(3) Å, β = 90°, R₁ = 0.0478, wR₂ = 0.0801.
