Abstract

Two equivalents of sulphur and selenium on reaction with 1,1'-bis(diphenylphosphino)ferrocene (dppf) resulted compound of composition [Fe{C5H4P(E)Ph2}2] (E = S, Se). The latter resulted phosphine derivative on reaction with NiCl2·6H2O afforded an additive product [NiCl2(dppfE2)] (dppf = Fe{C5H4PPh2}2; E = S, Se) which on further treatment with another equivalent of [NiCl2(dppfE2)] followed by the addition of sodium tetraphenylborate yielded a binuclear complex [Ni2(µ-Cl)2(dppfE2)](BPh4)2 (E = S, Se). All these complexes were characterized by elemental analysis, IR, 1H and 31P{1H} NMR spectroscopy. The molecular structure of [Fe{C5H4P(Se)Ph2}2] was determined by single crystal X-ray diffraction. The nanoparticles of complex [NiCl2{Fe(C5H4P(S)Ph2)2}] (1a) and [NiCl2{Fe(C5H4P(Se)Ph2)2}] (1b) was prepared through hydrothermal method. The resulting composites have further been applied for the catalytic oxidation of benzyl alcohol to aldehyde.

1,1'-双(二苯基硫属磷酰基)二茂铁类似物镍前体的合成及其催化氧化反应研究

摘要

两个当量的硫和硒与 1,1'-双(二苯基膦基)二茂铁 (dppf) 反应得到组成为 [Fe{C 5 H 4 P(E)Ph 2 } 2 ] (E = S, Se) 的化合物。后者在与 NiCl 2 ·6H 2 O 反应时产生膦衍生物,在进一步处理后得到添加剂产物 [NiCl 2 (dppfE 2 )] (dppf = Fe{C 5 H 4 PPh 2 } 2 ; E = S, Se)与另一当量的 [NiCl 2 (dppfE 2 )] 然后加入四苯基硼酸钠产生双核配合物 [Ni 2(µ-Cl) 2 (dppfE 2 )](BPh 4 ) 2 (E = S, Se)。所有这些配合物均通过元素分析、IR、1 H 和31 P{ 1 H} NMR 光谱进行了表征。[Fe{C 5 H 4 P(Se)Ph 2 } 2 ]的分子结构通过单晶X射线衍射确定。复合物[NiCl 2 {Fe(C 5 H 4 P(S)Ph 2 ) 2 }] ( 1a ) 和[NiCl 2 {Fe(C 5 H 4 P(Se)Ph)的纳米粒子2 ) 2 }] ( 1b ) 是通过水热法制备的。所得复合材料已进一步应用于苯甲醇催化氧化成醛。
