Reaction of organoantimony and organobismuth oxides (LSbO)(2) and (LBiO)(2) (where L is [2,6-bis(dimethylamino)methyl]phenyl) with four equivalents of the organoboronic acids gave new heteroboroxines LM[(OBR)(2)O] 1a-2c (for M = Sb: R = Ph (1a), 4-CF(3)C(6)H(4) (1b), ferrocenyl (1c); for M = Bi: R = Ph (2a), 4-CF(3)C(6)H(4) (2b), and ferrocenyl (2c)). Analogously, reaction between organotin carbonate L(Ph)Sn(CO(3)) and two equivalents of organoboronic acids yielded compounds L(Ph)Sn[(OBR)(2)O] (where R = Ph (3a), 4-CF(3)C(6)H(4) (3b), and ferrocenyl (3c)). All compounds were characterized by elemental analysis and NMR spectroscopy. Their structure was described both in solution (NMR studies) and in the solid state (X-ray diffraction analyses 1a, 1c, 2b, 3b, and 3c). All compounds contain a central MB(2)O(3) core (M = Sb, Bi, Sn), and the bonding situation within these rings and their potential aromaticity was investigated by the help of computational methods.
有机锑和有机铋氧化物 (LSbO)(2) 和 (LBiO)(2)（其中 L 是 [2,6-双（二甲氨基）甲基]苯基）与四当量的有机硼酸反应，得到了新的杂硼氧烷 LM[(OBR)(2)O] 1a-2c（对于 M = Sb：R = Ph（1a），4-CF(3)C(6)H(4)（1b），二茂铁基（1c）；对于 M = Bi：R = Ph（2a），4-CF(3)C(6)H(4)（2b），和二茂铁基（2c））。类似地，有机锡碳酸酯 L(Ph)Sn(CO(3)) 与两当量的有机硼酸反应，生成化合物 L(Ph)Sn[(OBR)(2)O]（其中 R = Ph（3a），4-CF(3)C(6)H(4)（3b），和二茂铁基（3c））。所有化合物均通过元素分析和 NMR 光谱进行了表征。它们的结构在溶液中（NMR 研究）和固态（X 射线衍射分析 1a、1c、2b、3b 和 3c）中均进行了描述。所有化合物均包含一个中心 MB(2)O(3)核心（M = Sb、Bi、Sn），并通过计算方法研究了这些环内的键合情况及其潜在的芳香性。
