Heterocycles as Ligands, XI. - Octamethyl-1,1′-diazaferrocene as a Bifunctional Nitrogen Base(C4Me4N)2 Fe·2 HNC4Me4 (3) reacts with Brønstedt and Lewis acids to give the adducts [(C4Me4N·E)2Fe]n+ [4 - 6, 11 - 13; n=2, E=H, CH3, CH3C(O); n=O, E=BH3, BF3, Fe(CO)4]. The stepwise substitution of the tetramethylpyrrole molecules in 3 leads to the complexes [(C4Me4N·E)(C4Me4N·E')Fe]n+ [16, 17, 19; n - O, E=C4Me4NH, E'=Fe(CO)4; n=1, E=BH3, E'=H; n=2, E=H, E'=CH3]. Similarly, the complexes [{(C4Me4N)C(O)CH2CH2C(O)(NC4me4}Fe]Cl2 (9) and [Ag2{μMe4N)2Fe}2Fe}2](BF4)2·2 MeOH (15) are obtained. Reaction of [(C4Me4NH)2Fe](BF4)2 (4) with nBuLi gives the protonated diazaferrocene [(C4Me4NH)(C4Me4N)Fe]BF4 (18) from which the dimeric iron diamide {(C4Me4N)2Fe}2 (20) is obtained on further deprotonation.
