摘要

在合成多用途前体 (NMe4)[Ni(CF3)3(MeCN)] 时，我们最近遇到了一个问题：在所选反应条件下，大量的 C2F5 取代 CF3 加入，形成了混合配体镍酸盐 [Ni(CF3)x(C2F5)y(MeCN)]- (x + y = 3)。我们利用 19F 核磁共振 (NMR) 光谱和单晶 X 射线衍射研究了 y = 0、1 或 2 的三种产物。通过修改实验条件，我们追溯到了反应机理并解决了问题。

Synthesis of Tris(trifluoromethyl)nickelates(II)—Coping with “The C2F5 Problem”

When synthesizing the versatile precursors (NMe4)[Ni(CF3)3(MeCN)] we recently encountered the problem that marked amounts of C2F5 were incorporated instead of CF3 under the chosen reaction conditions forming mixed-ligand nickelates [Ni(CF3)x(C2F5)y(MeCN)]− (x + y = 3). We studied the three products with y = 0, 1, or 2, using 19F nuclear magnetic resonance (NMR) spectroscopy and single-crystal X-ray diffraction. We were able to trace the reaction mechanism and solve the problem by modifying the experimental conditions.
