Cymantrene- and Ferrocene-Based Complexes with Perfluorinated Bridging Moieties

Trifluorovinylcymantrene (1) and -ferrocene (2) form the basis of a versatile building block chemistry. Di- and trinuclear complexes with perfluorinated bridging moieties are obtained by [2+2] cycloaddition on 1 and nucleophilic substitution on the C2F3 unit of 2 with cymantrenyllithium.

三氟乙烯基环戊二烯三羰基锰（Trifluorovinylcymantrene，化合物1）与三氟乙烯基二茂铁（Trifluorovinylferrocene，化合物2）构成了多功能结构基元化学的基础。通过对化合物1进行[2+2]环加成反应，以及利用环戊二烯三羰基锰锂（cymantrenyllithium）对化合物2的C₂F₃单元实施亲核取代，可得到带有全氟化桥联基团的双核与三核配合物。
