Abstrakt: The syntheses and characterizations of the first bismuthanylborane monomers stabilized only by a donor in D·BH 2 Bi(SiMe 3 ) 2 (D = DMAP 1a, IDipp 1b, IMe 4 1c; DMAP = 4-dimethylaminopyridine, IDipp = 1,3-bis(2,6-diisopropylphenyl)-imidazolin-2-ylidene, IMe 4 = 1,3,4,5-tetramethylimidazol-2-ylidene) are presented. All compounds were synthesized by salt metathesis reactions between D·BH 2 I and KBi(SiMe 3 ) 2 (THF) 0.3 and represent some of the extremely rare compounds featuring a 2c-2e B-Bi bond in a molecular compound. The products display high sensitivity towards air and light and slowly decompose in solution even at -80 °C. By the reaction of IDipp·GaH 2 (SO 3 CF 3 ) with KBi(SiMe 3 ) 2 (THF) 0.3 , the synthesis of the first bismuthanylgallane IDipp·GaH 2 Bi(SiMe 3 ) 2 (2) stabilized only by a 2-electron donor was possible, as evident from single crystal X-ray structure determination, NMR spectroscopy and mass spectrometry. Computational studies shed light on the stability of the products and the electronic nature of the compounds.
