As part of our ongoing interest in the synthesis and reduction chemistry of organoboron species, we have investigated the synthesis of mixed organoboron/organomercury complexes by reaction of the Li(THF)4 salt of dimesityl-1, 8-naphthalenediylborate with 1, 2-(HgCl)2C6F4 and 1, 3-(HgCl)2C6F4, respectively. The resulting tetranuclear B2Hg2 complexes (2 and 3, respectively) were characterized by multinuclear
作为我们对有机硼物种的合成和还原化学的持续兴趣的一部分,我们研究了通过 Dimesityl-1, 8-naphthalenediylborate 的 Li(THF)4 盐与 1, 2- (HgCl)2C6F4 和 1, 3-(HgCl)2C6F4。所得四核 B2Hg2 配合物(分别为 2 和 3)通过多核 NMR 光谱和单晶 X 射线分析进行表征。复合物 2 的循环伏安图,其特征是 B–Hg–Hg-B 核由邻亚苯基(Hg–Hg 连接)和两个邻萘二基连接体(B–Hg 连接)连接,显示了两种电活性的显着耦合硼基单元,大概是通过四个相邻路易斯酸的空 p 轨道的直接 σ 相互作用。这个结论得到了 DFT 计算的支持,
