The ferrocene based aminopyridine “ligand” fc(Me 2 SiApH) 2 ( 3 ), fc(Me 2 SiApH) 2 = 1,1′‐bis{[(N‐4‐methylpyridin‐2‐yl)amino]dimethylsilyl}ferrocene, has been synthesized by the reaction of 1,1′‐bis(chlorodimethylsilyl)ferrocene ( 1 ) with the sodium salt of 4‐methyl‐2‐aminopyridine in hexane. Compound 1 is accessible by the reaction of 1,1′‐dilithioferrocene with a fortyfold excess of Me 2 SiCl 2 . The reactions of 3 with one equiv of Ti(NMe 2 ) 4 or ClTi(NMe 2 ) 3 , resp. afford the corresponding bimetallic titanium complexes fc(Me 2 SiAp) 2 Ti(NMe 2 ) 2 ( 4 ) or fc(Me 2 SiAp) 2 Ti(NMe 2 Cl ( 5 )), resp. The crystal structure of 3 is reported.
