报道了路易斯碱稳定的苯乙烯基硼烷单体母体化合物“H2SbBH2”的合成。通过盐复分解路线,合成了甲硅烷基取代的化合物(Me3Si)2SbBH2⋅LB (LB=NMe3, NHCMe)作为具有SbB σ 键的衍生物的代表。在非常温和的条件下,它们可以分别转化为目标化合物Me3N⋅H2BHSbBH2⋅NMe3和H2SbBH2⋅NHCMe。通过X射线结构分析、核磁共振波谱、红外光谱和质谱对产物进行了表征。 DFT 计算可以进一步深入了解这些独特化合物的稳定性和键合。
The synthesis of the Lewis base stabilized monomeric parent compound of stibanylboranes, “H2SbBH2”, is reported. Through a salt metathesis route, the silyl‐substituted compounds (Me3Si)2SbBH2⋅LB (LB=NMe3, NHCMe) were synthesized as representatives of derivatives with a SbB σ bond. Under very mild conditions, they could be transformed into the target compounds Me3N⋅H2BHSbBH2⋅NMe3and H2SbBH2⋅NHCMe, 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.
