The first germaphosphaallene, 3, has been obtained by debromofluorination of the (fluorogermyl)bromophosphaalkene 7 and characterized by P-31 NMR (240 ppm) and C-13 NMR (280.9 ppm for the allenic carbon) at low temperature. Methanol and methyllithium react exclusively with the Ge=C double bond to afford the corresponding adducts 9 and 10. In the absence of a trapping reagent, 3 gives two types of dimer, 13a (involving two Ge=C bonds) and 14a (involving one Ge=C and one P=C bond).
