A series of tris-, bis-, and mono(pentafluoroethyl)bismuthanes of the type (C2 F5 )n BiX3-n (X=F, Cl, Br, I) and transition metal complexes are accessible by a sophisticated pentafluoroethylation protocol. Chemical properties, induced by the strongly electron-withdrawing character of C2 F5 groups, are described for representative examples. Moreover, the first molecular structures of perfluoroalkyl bismuthanes and bismuthates obtained by X-ray diffraction are presented.
Keywords: alkylation; bismuth; fluorinated ligands; fluorine; synthetic methods.
