The synthesis of stable monomeric dimesityloxygermylene-amine (MesO)2Ge-NR3 [NR3 = Et2NH, (C6H11)2NH, Et3N, dabco, tmeda] and chloromesityloxygermylene-amine MesO(Cl)Ge-tmeda complexes is presented. All compounds have been fully characterized by spectroscopic methods. Theinsertion reaction of (MesO)2Ge-tmeda 1a with dimethyl disul fide, bis(trimethylsilyl)peroxide and iodomethane is reported. Cycloaddition reactions with dimethylbutadiene are especially effective without any activation and with dimethyl acetylenedicarboxylate led selectively to compounds 7 and 8. In the latter case, the transient formation of a germirene has been evidenced by a trapping reaction. The structures of 3, 7 and 8 were determined by single-crystal X-ray diffraction.
