[(FcdippN) 2 MoCl 2 (DME)] ( 1 ) was used as starting material for the synthesis of the novel ferrocenyl‐functionalised complexes [(FcdippN) 2 Mo(CH 2 CMe 2 Ph) 2 ] ( 2 ), [(FcdippN) 2 Mo(OTf) 2 (DME)] ( 3 ), and [(FcdippN)Mo(CHCMe 2 Ph)(O t Bu) 2 ] ( 4 ) (Fcdipp = 4‐ferrocenyl‐2,6‐diisopropylphenyl). The crystal structure of 2 was determined. Electrochemical investigations by cyclic voltammetry suggest a communication of the ferrocenyl unit and the molybdenum centre in these compounds. The monoalkylation of [(DippN) 2 MoCl 2 (DME)] ( 5 ) to [(DippN) 2 Mo(CH 2 CMe 2 Ph)Cl] ( 6 ) (Dipp = 2,6‐diisopropylphenyl) was achieved.
