Zusammenfassung
The synthesis of the Lewis base stabilized monomeric parent compound of stibanylboranes, H2SbBH2, is reported. Through a salt metathesis route, the silyl-substituted compounds (Me3Si)(2)SbBH2LB (LB=NMe3, NHCMe) were synthesized as representatives of derivatives with a SbB sigma bond. Under very mild conditions, they could be transformed into the target compounds Me3NH2BHSbBH2NMe3 and ...

The synthesis of the Lewis base stabilized monomeric parent compound of stibanylboranes, H2SbBH2, is reported. Through a salt metathesis route, the silyl-substituted compounds (Me3Si)(2)SbBH2LB (LB=NMe3, NHCMe) were synthesized as representatives of derivatives with a SbB sigma bond. Under very mild conditions, they could be transformed into the target compounds Me3NH2BHSbBH2NMe3 and H2SbBH2NHCMe, respectively. The products were characterized by X-ray structure analysis, NMR spectroscopy, IR spectroscopy, and mass spectrometry. DFT calculations give further insight into the stability and bonding of these unique compounds.
