摘要：

We report on the synthesis and characterization of mixed pnictogenylboranes. The substitution of the Lewis base SMe2 in (OC)(5)W-PH2BH2-SMe2 (2) by different pnictogenylboranes ER2BH2-LB (E=P, As, Sb) leads to the Lewis acid/base stabilized butane analogue (OC)(5)W-PH2BH2ER2BH2-LB (3a,b: E=P; R=H, SiMe3; LB=NMe3; 4a,b: E=As; R=H, SiMe3; LB=NMe3; 5: E=Sb; R=SiMe3; LB=NHCMe). All of these compounds were characterized by single-crystal X-ray structure analysis, mass spectrometry, NMR, and IR spectroscopy. In addition, the very unstable phosphanylborane chain PH2BH2PH2BH2-NMe3 (1) was synthesized. DFT calculations provide insight into the thermodynamics of these reactions.
