摘要

在此，我们报道了双（氢三（吡唑基）硼酸盐）（Tp*）铀（III）配合物的合成，该配合物激活并开环了四氢呋喃（THF）分子。以Tp*2UBn （1-Bn）和仲嘌呤为原料合成了Tp*2UO(CH2)4PPh2 （1-PPh2）、Tp*2UO(CH2)4PMes2 （1-PMes2）和Tp*2UO(CH2)4AsMes2 （1-AsMes2）。通过1H NMR、单晶x射线衍射、电子吸收光谱和红外光谱对这些配合物进行了表征。THF环开口的出现表明U（III）偏爱电负性氧原子，而不是较软的氧原元素。

THF Activation from the Synthesis of Reactive Uranium(III)-Pnictogen Bonds

Herein, we report the synthesis of bis(hydrotris(pyrazolyl)borate) (Tp*) uranium(III) complexes that have activated and ring-opened a tetrahydrofuran (THF) molecule. Using Tp*₂UBn (1-Bn) and secondary pnictines, a family of compounds was synthesized, Tp*₂UO(CH₂)₄PPh₂ (1-PPh₂), Tp*₂UO(CH₂)₄PMes₂ (1-PMes₂) and Tp*₂UO(CH₂)₄AsMes₂ (1-AsMes₂). These complexes were characterized by ¹H NMR spectroscopy, single crystal X-ray diffraction, electronic absorption spectroscopy, and IR spectroscopy. The occurrence of the THF ring opening demonstrates the preference of U(III) for the electronegative oxygen atom as opposed to the softer pnictogen elements.

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.
