摘要

摘要三氨基(三羰基)铬(I)与 1,3-苯并二恶烷(L1)、2-甲基-1,3-苯并二恶烷(L2)和 2-苯基-1,3-苯并二恶烷(L3)反应生成新的配合物：(η6-C8H8O2)Cr(CO)3 (II)、外向和内向[2-Me-(η6-C8H7O2)]Cr(CO)3 (III，IV)、外向和内向[2-Ph-(η6-C8H7O2)]Cr(CO)3 (V、VI）、[2-(η6-Ph)-C8H7O2]Cr(CO)3（VII）和内向[2-(η6-Ph)]Cr(CO)3-[η6-C8H7O2]Cr(CO)3（VIII）。紫外光谱、红外光谱、1H NMR 光谱、高效液相色谱和质谱法证明了合成产物的结构、组成和纯度。络合物 IV-VI 的分子结构是通过 XRD 确定的（CIF 文件 CCDC 编号：2263301（IV）、2295552（V）和 2237106（VI））。结果表明，三羰基铬有可能配位在配体 L2 和 L3 苯环的不同侧面以及配体 L3 的苯基取代基上。

Synthesis of (η6-Arene)tricarbonylchromium Complexes of 1,3-Benzodioxanes

The reactions of triammino(tricarbonyl)chromium (I) with 1,3-benzodioxane (L¹), 2-methyl-1,3-benzodioxane (L²), and 2-phenyl-1,3-benzodioxane (L³) afford new complexes: (η⁶-C₈H₈O₂)Cr(CO)₃ (II), exo- and endo-[2-Me-(η⁶-C₈H₇O₂)]Cr(CO)₃ (III, IV), exo- and endo-[2-Ph-(η⁶-C₈H₇O₂)]Cr(CO)₃ (V, VI), [2-(η⁶-Ph)-C₈H₇O₂]Cr(CO)₃ (VII), and endo-[2-(η⁶-Ph)]Cr(CO)₃-[η⁶-C₈H₇O₂]Cr(CO)₃ (VIII). The structures, compositions, and purity of the synthesized products are proved by UV, IR, and ¹H NMR spectroscopy, HPLC, and mass spectrometry. The molecular structures of complexes IV–VI are determined by XRD (CIF files CCDC nos. 2263301 (IV), 2295552 (V), and 2237106 (VI)). A possibility of coordination of the tricarbonylchromium group at different sides of the phenylene ring of ligands L² and L³ and on the phenyl substituent of ligand L³ is shown.
