A facile synthesis of 1-halo- and 1-organoxygermatranes

Interaction of the readily available 1-trimethylsiloxygermatranes (1a, 1b) with various halogenating reagents (Me3SiBr, Me3SiI, HF and SOCl2) has given the 1-halogermatranes (2a-2f).The 1-halogermatranes (2a, 2b) have been converted into the corresponding 1-organoxygermatranes by treatment with trialkylalkoxystannanes (3a-3f).The corresponding 1-organoxygermatranes (4d, 4e, 4f) were made by interaction of 1-hydroxygermatrane monohydrate with the corresponding hydroxy derivatives).
