The optimal conditions for the catalytic reduction of DAF-1 to DAP-2 were found: catalyst, hydrogen pressure, reaction temperature, solvent, concentrations of the starting compound and the ratio of the catalyst and starting DAF-1. The laboratory regulations for the catalytic reduction of DAF-1 in DAP-2 were issued and handed over to the customer. Based on the analysis of collected literature data, it is established that there are two synthetic approaches to 1,1'-disubstituted silylferrocenes. One of them consists in the functionalization of organometallic derivatives of ferrocene with organosilicon electrophile. 1,1'-Disubstituted silylferrocenes were prepared by the reaction of 1,1'-dilithioferrocene with various chlorosilanes. The second approach is based on the synthesis of silylfunctionalized cyclopentadiene followed by its conversion to the corresponding ferrocene by condensation with a ferrous derivative. Thus, the most technological method for the production of ferrocenylsilanes is based on the interaction of anhydrous ferric chloride and silylcyclopentadiene in an organic solvent in the presence of methylate, ethylate or sodium isopropylate as a deprotonating agent.
