with Ge[N(SiMe3)2]2 or Sn[N(SiMe3)2]2 to give the protic benzimidazolin-2-germylenes 2a–d or the benzimidazolin-2-stannylenes 3a,b. Germylenes 2a,b can be deprotonated to give the salts Na-4a and Na-4b, each containing an anionic N-deprotonated N-heterocyclicgermylene. The protic stannylenes 3a,b react with NaH presumably via reduction of the tin(II) center by the deprotonated electron-rich o-phenylenediamine
