摘要

在这里，我们描述了一个独特的例子，低价单配位Bi(I)配合物在FLP激活反应中作为路易斯碱伴侣。体积大且刚性的Bi(I)与Lewis酸性三（五氟苯基）硼烷（BCF）之间的相互作用使四氢呋喃（THF）打开，产生两性离子Bi(+)/B（−）产物，该产物可以通过光谱和SC-XRD分离和表征。两性离子铋配合物在可见光范围内表现出显著的光谱特征，即从芳香族芴向高度缺电子的阳离子铋中心过渡的LMCT波段。有趣的是，该带的激发导致闭合环的C-O键形成和随后的Bi(I)的恢复，从而构成与铋的光可逆FLP活化。

Flash Communication: Bismuthinidenes as Lewis Bases in Reversible C(sp3)–O Bond Cleavage

Herein, we describe a unique example of a low-valent monocoordinated Bi(I) complex acting as a Lewis base partner in a FLP activation reaction. The interplay between a bulky and rigid Bi(I) and the Lewis acidic tris(pentafluorophenyl)borane (BCF) enables the opening of tetrahydrofuran (THF), delivering a zwitterionic Bi(+)/B(−) product, which could be isolated and characterized spectroscopically and through SC-XRD. The zwitterionic bismuth complex exhibits remarkable spectroscopic features in the visible range, namely an LMCT band corresponding to the transition from the aromatic fluorene to the highly electron-poor cationic bismuth center. Interestingly, excitation of this band results in ring-closing C–O bond formation and subsequent recovery of the Bi(I), thus constituting a photoreversible FLP activation with bismuth.

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
