The synthesis, characterization and reactivity studies of the NHC-stabilized complex IDipp . GeH2BH2OTf (1) (IDipp=1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) are reported. Nucleophilic substitution of the triflate (OTf) group in 1 by phosphine or arsine donors provides access to the cationic group 13/14/15 chains [IDipp . (GeH2BH2ERRR2)-R-1](+) (2 E=P; R, R-1=H; R-2=Bu-t; 3 E=P; R=H; R-1, R-2=Ph; 4 a E=P; R, R-1, R-2=Ph; 4 b E=As; R, R-1, R-2=Ph). These novel cationic chains were characterized by X-ray crystallography, NMR spectroscopy and mass spectrometry. Moreover, the formation of the parent complexes [IDipp . GeH2BH2PH3][OTf] (5) and [IDipp . GeH3][OTf] (6) were achieved by reaction of 1 with PH3. Accompanying DFT computations give insight into the stability of the formed chains with respect to their decomposition.
