Abstract / Bemerkung
This paper gives an account on hypervalent fluoro- and chloro(pentafluoroethyl)germanium compounds. The selective synthesis of the tris(pentafluoroethyl)dichlorogermanate salt [PNP][(C2F5)(3)GeCl2] as well as its X-ray structural analysis is described. As a representative example for pentafluoroethylfluorogermanates, the synthesis and structure of 2,4,6-triphenylpyryliumtris(pentafluoroethyl)difluorogermanate [C23H17O][(C2F5)(3)GeF2] is reported. Fluoride-ion affinities for pentafluoroethylgermanes were calculated using quantum chemical methods, disclosing (C2F5)(3)GeF as a weaker Lewis acid than (C2F5)(3)SiF or (C2F5)(3)PF2. The theoretical results were confirmed by experiments and give the basis of a synthetic protocol for (C2F5)(3)GeF. Pentakis(pentafluoroethyl)germanate [PPh4][Ge(C2F5)(5)] was detected as an intermediate during the synthesis of [PPh4][(C2F5)(4)GeF] starting from tris(pentafluoroethyl)difluorogermanate and LiC2F5.
