摘要：

"Chemical Equation Presented" SiCl2 as a simultaneous σ-donor and acceptor: The reaction of the Lewis base stabilized dichlorosilylene L → SiCl2 with B(C6F 5)3 (L = imidazol-2-ylidene derivative) afforded the first silylene donor acceptor L→SiCl2→B-(C6F 5)3 complex (shown here). Charge density analysis revealed that the two C→Si and Si→ B donor bonds are of considerably different quality. However, plain bond length consideration might suggest simple C-Si and Si-B single bonds. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
