One-pot reaction of FcCH(R)OH with equimolar quantities of BunLi and EtOCOCl followed by an excess of amine produces N-(α-ferrocenylalkyl)amines in up to 98% yields. Nitrogen heteroaryl amines undergo the α-ferrocenylalkylation at the amino group. The α-ferrocenylalkylation of alcohols and phenols (R'OH) leads to a formation of ethers FcCH(R)OR′ in lower yields. The reactions proceed via an intermediate formation of α-ferrocenylalkyl carbonates FcCH(R)OCOOEt. The side reactions associated with this protocol are discussed.

Paragraph 0050; 0053, (2018/09/11)
The invention discloses a process for preparing (S)-1-ferrocene ethyl dimethylamine. In the preparation process, acetylferrocene is used as a raw material, and a complex obtained by reacting a metal Ir complex with a chiral ferrocene tridentate ligand L* is used as a catalyst, (S)-1-ferrocenyl ethanol is prepared by asymmetric catalytic hydrogenation, and the(S)-1-ferrocene ethyl dimethylamine isprepared by acetylation and dimethylamine substitution reaction. Compared with a traditional chiral separation method for preparing the (S)-1-ferrocene ethyl dimethylamine, the process has main beneficial effects of mild reaction conditions, simple operation, good stereoselectivity, high yield, short production cycle, small amount of three wastes , easy industrialization, and large implementationvalue and social and economic benefits.
