Abstract:

C5H5Fe(C4Me4N) (I) is obtained by deprotonation of the pyrrole complex [C5H5Fe(C4Me4NH)]BF4. The nitrogen basicity of I resembles closely that of alkylpyridines (pKa = 7.2). I reacts with Lewis acids to give the adducts [C5H5Fe(C4Me4NR)]+ (R = Me, Ac) and C5H5Fe(C4Me4NE) [E = BH3 (II), Fe(CO)4]. The x-ray structure of II is isosteric with pentamethylferrocene and has a metallocene structure with an eclipsed ligand conformation.
