Abstract

Oxidation of a bis-stibinoaryl amine (2) with chloranil leads first to formation of a crystallographically observed bis-stiboranoraryl amine (3a) which then undergoes isomerization to an ionic tetraarylstibonium antimonate (3b). The isomerization proceeds at different rates in different solvents, but a univariate explanation of solvent effects is not evident. The antimonate anion in 3b can be exchanged for a fluoride, resulting in a neutral fluorostiborane (4), and further to a triflate in an ionic tetraarylstibonium triflate (5). Compound 5 displays strong binding of fluoride in tetrahydrofuran. Structures of 3a, 3b, 4, and 5 were determined by single-crystal X-ray diffraction.

双二氨基苯并呋喃氧化时的自发再分布

双链烷芳基胺（2）与氯苯的氧化反应首先会形成晶体学上观察到的双链烷芳基胺（3a），然后发生异构化为离子型四芳烷基锑酸酯（3b）。在不同溶剂中，异构化的速度不同，但溶剂影响的单变量解释并不明显。3b 中的锑酸根阴离子可以与氟化物交换，生成中性的氟芪 (4)，并进一步与三酸酯交换，生成离子型四芳基芪三酸酯 (5)。化合物 5 在四氢呋喃中显示出很强的氟化物结合力。通过单晶 X 射线衍射确定了 3a、3b、4 和 5 的结构。

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
