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

Abstract

The title compound FcCH(t-Bu)NHCH(Me)-CH 2 OMe´LiI´Et 2 O (1´LiI´Et 2 O) was obtained by reaction of FcCH(t-Bu)N(Li)CH(Me)CH 2 OMe 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 coordi-nate 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´Et 2 O: Space group P2 1 2 1 2 1 , Z = 4, lattice dimensions at ±60°C: a = 10.492(2), b = 13.225(2), c = 18.846(3) A Ê , b = 90°, R 1 = 0.0478, wR 2 = 0.0801.
