The first organogermanium dendrimers were synthesized by using diverge
nt and convergent routes. The principal reactions used for these synth
eses are hydrogermylation or hydrozirconation-transmetalation. These d
endrimers were characterized by their IR, H-1 NMR and C-13 NMR spectra
and by the MALDI mass spectra of their adducts with suitable thioeste
rs.
