Extensive analytical studies of the processes of synthesis of ferrocene and its alkyl derivatives of known methods and identified the possible side and parallel chemical reactions in the interaction between the main and auxiliary agents, as well as working (ammonium) environment. Suggested ways to prevent adverse reactions and side in the synthesis of desired products. To increase the reactivity of the suspension of sodium amide instead of liquid ammonia proposed tetrahydrofuran, and instead of anhydrous ferric chloride ammine iron suspension in hexane
