  摘要：

  2,2,2-Triphenyl-1,3,2-benzodioxastibolanes react with alcohols, phenols, and amines in the presence of copper salts to give the corresponding O- and N-phenyl derivatives. Cyclic Sb-V dialkoxide containing an electron-withdrawing nitro group in the dioxastibolane fragment is most reactive in N-phenylation of primary and secondary amines. Organoantimony analogs containing electron-donating groups are more efficient in O-phenylation of primary and secondary alcohols and phenols.

  Oxidation of elemental antimony by substituted ortho-benzoquinones

  摘要：

  The oxidation of elemental antimony by the o-quinones Y4C6O2-o (Y = Cl or Br) in diethyl ether gives the unusual antimony(v) products Sb(O2C6Y4)2.5.nEt2O (Y = Cl, n = 1.5; Y = Br, n = 1). The same quinones, and 3,5-di-tert-butyl-1,2-benzoquinone, upon treatment with Sb + 1/2X2 (X = Br or 1) in toluene, give the antimony(III) derivatives Sb(cat)X (cat = substituted catecholate anion). The oxidations are shown by electron spin resonance spectroscopy to proceed via the o-semiquinone intermediates. Adducts of Sb(cat)l with bidentate neutral donors have been prepared. The structure of Sb(dbc)I(bipy) (dbc = 3,5-di-tert-butylcatecholate, bipy = 2,2'-bipyridine) has been shown to be that of a pseudo-octahedral molecule with a stereochemically active lone pair of electrons. Crystal parameters for Sb(dbc)I(bipy).0.5bipy: triclinic, space group P1BAR, a = 9.779(4), b = 18.554(7), c = 8.944(3) angstrom, alpha = 100.94(3), beta = 115.11(3). gamma = 86.82(4)-degrees, Z = 2 and R = 0.044 for 3307 unique reflections.

  Recently the ability of complexes of non-transition metals to reversibly add molecular oxygen was found by the example of о-amidophenolate and catecholate (Cat) complexes of triphenyl antimony(V) with donor methoxy groups in the 4 and 5 positions of the aromatic ring of the catecholate ligand [1, 2]. Variation in the nature of the substituents in the Cat ligand affects the reactivity of these compounds

  最近，通过在芳环的 4 位和 5 位具有供体甲氧基的三苯基锑 (V) 的 о-amidophenolate 和儿茶酚 (Cat) 络合物的例子，发现了非过渡金属络合物可逆地添加分子氧的能力儿茶酸盐配体 [1, 2]。Cat 配体中取代基性质的变化会影响这些化合物对氧的反应性：吸电子基团的引入导致形成空气稳定的儿茶酚盐，而电子给体基团的存在使这些配合物有可能添加分子氧[3-7]。对配合物电化学性质的研究表明，Cat 配体中的受体基团将邻苯二甲酸盐的氧化电位转移到正电区域（阻碍阳极过程）并降低阳离子配合物的稳定性；供体取代基，反之亦然，促进了 Cat 配体与分子氧的氧化（将氧化电位转移到阴极场），有利于与氧的相互作用。然而，目前文献中没有关于锑原子处的氧化还原惰性有机片段对式 (Cat)SbAr3 配合物中 Cat 配体氧化还原转化的影响的数据。促进 Cat 配体与分子氧的氧化（将氧化电位转移

  interaction were investigated in the example of complex 5. The electrochemical behavior of the complexes depends on the coordinated N-donor ligand. The coordination of pyrazine, Bipy, and PySSPy at the antimony atom changes their mechanism of electrooxidation: instead of two successive redox stages Cat/SQ and SQ/Cat, one multielectron stage was observed. The coordination of the DABCO ligand is accompanied
