Diphosphanylmetallocenes of Main-Group Elements
Several 1,1’-diphosphanyl-substituted metallo cenes of magnesium (magnesocenes) were synthesized,
structurally characterized, and their reactivity and coordina tion chemistry were investigated. Transmetalation of these
magnesocenes gives access to group 14 metallocenes (tetre locenes), as well as to group 15 stibonocenes. These s- and
p-block metallocenes represent a novel class of bis(phos phanyl) ligands, exhibiting Lewis-amphiphilic character. Their
coordination chemistry towards different transition-metal
and main-group fragments was investigated and different
complexes are presented
Bis(di-tert-butylindenyl)tetrelocenes
The synthesis and characterization of bis(di-tert-butylindenyl) germanium(II), tin(II) and lead(II) complexes are reported, which includes the first structurally authenticated example of a bis(indenyl)germanocene. The species were studied in detail in solution and in the solid, which includes single crystal X-ray diffraction and NMR spectroscopy, as well as Mössbauer spectroscopy of the tin compound
