The monoalkylated or monoarylated o-phenylenediamines 1a-d (1a, R = t-Bu; 1b, R = adamantyl; 1c, R = phenyl; 1d, R = mesityl) react via transamination 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-heterocyclic germylene. The protic stannylenes 3a,b react with NaH presumably via reduction of the tin(II) center by the deprotonated electron-rich o-phenylenediamine ligand and release of elemental tin. To prevent this reduction, the electron-poor N-H,N′-H-5,6-dibromobenzimidazolin-2-stannylene (5) was prepared and successfully N-deprotonated to give an anionic stannylene in Na-6. The molecular structures of 2a, 3a, and Na-4a were established by X-ray diffraction studies. (Chemical Presented).

A series of bis- and tris(oxobenzimidazolyl)hydroborato compounds, namely, [BoRBenz]Na and [ToRBenz]-Na (R = Me, But, Ad), which feature uncommon sterically demanding LX [O2] and L2X [O3] d
One-pot N-acylation and N-alkylation of o-nitroaniline with saturated hydrocarbons in the presence of carbon monoxide
Akhrem, Irena S.,Avetisyan, Dzhul'Etta V.,Kagramanov, Nikolai D.,Petrovskii, Pavel V.,Mysova, Nadezhda E.
body text, p. 257 - 259 (2011/05/17)
The first one-pot N-acylations and N-alkylations of o-nitroaniline with saturated hydrocarbons were performed in the presence of superelectrophiles; the role of CO in the alkylation with n-pentane is discussed.
Adamantylation of nitro-substituted aromatic amines in protic acids
Volkova,Platonova,Tsypin,Polukeev
experimental part, p. 1719 - 1727 (2009/02/06)
Adamantylation of mono-and dinitro-substituted aromatic amines in sulfuric and phosphoric acids and in a mixture of phosphoric and acetic acids gives mainly the corresponding N-adamantyl derivatives. The results of kinetic measurements showed reversible c
