Boron compounds have attracted the attention of chemists because of their unique catalytic properties and potential wider material applications. Although group 13 metal compounds, which are based on the bis-(benzoxazol-2-yl)-methane system (Box, ({NCOC₆H₄}₂CH₂)), have been reported in the last several years, boron containing Box compounds were still missing. Now we report their successful syntheses and spectroscopic characterisation in this work. The borane compound [({NCOC₆H₃}₂CH)BH₂] (1) and haloboranes [({NCOC₆H₃}₂CH)BF₂] (2), [({NCOC₆H₃}₂CH)BCl₂] (3) and [({NCOC₆H₃}₂CH)BBr₂] (4) were characterised in the solid state by single crystal X-ray diffraction and in solution by NMR techniques. In addition, the fluorescence properties of compounds 1–4 are communicated.

双-(4-甲基苯并恶唑-2-基)-甲烷化硼配合物

硼化合物因其独特的催化性能和潜在的更广泛的材料应用而引起了化学家的关注。尽管基于双-(苯并恶唑-2-基)-甲烷体系(Box, ({NCOC ₆ H ₄ } ₂ CH ₂ ))的第13族金属化合物在过去几年已有报道，但含硼盒子化合物仍然失踪。现在我们在这项工作中报告他们的成功合成和光谱表征。硼烷化合物 [({NCOC ₆ H ₃ } ₂ CH)BH ₂ ] ( 1 ) 和卤代硼烷 [({NCOC ₆ H ₃ } ₂ CH)BF ₂ ] ( 2 )、[({NCOC ₆ H ₃ } ₂ CH) )BCl ₂ ] ( 3 ) 和 [({NCOC ₆ H ₃ } ₂ CH)BBr ₂ ] ( 4 ) 在固态中通过单晶 X 射线衍射进行表征，在溶液中则通过 NMR 技术进行表征。此外，还传达了化合物1-4的荧光特性。
