Abstract

The reactions of chloro-silicon- and chloro-germanium-transition metal complexes with AgBF4, AgPF6, and AgSbF6 produce, in high yield, the corresponding fluoro derivatives and BF3, PF3, and SbF5, respectively. Secondary reactions involving the cleavage of silicon- and germanium-to-carbon bonds by PF5 and SbF5 are also observed. With chloro-tin-transition metal compounds, AgBF4 yields covalent complexes in which BF4- is coordinated to tin. The reaction of (C5 H5)Fe-(CO)2Si(OCH3)3 with HPF6 also results in fluoro-silicon derivatives. In no case could a cationic silylene, germylene, or stannylene complex be isolated, and the reasons for the preferential fluorination are discussed in comparison with results for analogous carbenoid systems.
