We report the synthesis of H2 B(pz)2 PR , H2 C(pz)2 PR , HB(pz)3 P , and HC(pz)3 P (H2 B(pz)2 =bis(pyrazolyl)borate; H2 C(pz)2 =bis(pyrazolyl)methane; HB(pz)3 =tris(pyrazolyl)borate; HC(pz)3 =tris(pyrazolyl) methane; R=Ph, Cy or Et2 N) by reaction of the corresponding neutral or anionic ligands with chlorophosphines in the presence of TMSOTf. The structures of these compounds were determined by X-ray crystallographic analysis and the nature of their bonding was examined using density functional theory.
我们报道了通过相应的中性或阴离子配体与氯膦在三甲基硅基三氟甲磺酸酯（TMSOTf）存在下反应合成H2B(pz)2PR、H2C(pz)2PR、HB(pz)3P和HC(pz)3P（H2B(pz)2 = 双（吡唑基）硼酸酯；H2C(pz)2 = 双（吡唑基）甲烷；HB(pz)3 = 三（吡唑基）硼酸酯；HC(pz)3 = 三（吡唑基）甲烷；R = Ph、Cy 或 Et2N）。通过 X 射线晶体学分析确定了这些化合物的结构，并使用密度泛函理论研究了它们的键合性质。
