  The reaction of Veith's germylene Me(2)Si((t)BuN)(2)Ge 1 with an excess of organic azides R-N-3 2a-2i under elimination of N-2, very probably gives the unstable, reactive germaimines Me(2)Si((t)BuN)(2)Ge=N-R that dimerize rapidly even at -40 degrees C, yielding the dispirodecanes 4a-4g. At higher temperatures, however, the [2 + 3] dipolar cycle-addition of a second molecule of R-N-3 leading to 5-germa tetrazolines, 3a-3e, competes successfully. This depends on the nature of R, and is thermally reversible. Other scavengers are, e.g. Me(3)Sn-Cl or Me(3)Si-N-3. With the corresponding Veith-stannylene 5, only dispiro compounds 4h-4k are obtained, and no 5-stanna tetrazoline. 1 and 5 exhibit, however, the same activity toward p-tolyl azide, leading, in a competitive experiment, to a statistical 1:1:2 distribution of the Ge-2, Sn-2, and Ge, Sn (41) dispirodecanes. The stability of the tricyclic system 4 in most of the examples is very high. Thus, in the mass spectra of 4b, 4k, 4l the molecular peaks M(+) (m/z = 756, 848, 802) are the respective base peaks, followed by (M-Me)(+). Doubly loaded ions (M-2Me)(2+) are also surprisingly stable. Most of the obtained compounds are new.
