Abstract

The reaction of bisgermavinylidene [(Me₃SiN=PPh ₂)₂C=Ge→Ge=C(PPh₂=NSiMe₃) ₂] (1) with AdNCO (Ad = Adamantyl) afforded the [2 + 2] cycloadditon product [(Me₃SiN=PPh₂)₂CGeC(O) NAd] (2). Similar reaction of 1 with Ph₃SiOH in tetrahydrofuran (THF) yielded the base-stabilized germanium(II) triphenylsiloxide [H₂C(PPh ₂=NSiMe₃)₂Ge(OSiPh₃)₂] (3). The results suggested that reactive germavinylidene may exist in solution and is capable of forming addition reaction products. The X-ray structures of 2 and 3 were determined.
