Fundamental Study on Arsenic(III) Halides (AsX<sub>3</sub>; X = Br, I) toward the Construction of <i>C</i><sub>3</sub>-Symmetrical Monodentate Arsenic Ligands
Arsenicligands have attracted considerable attention in coordination chemistry. Arsenic(III) halides are the most important starting materials in the preparation of monodentate arsenicligands. In this work, we optimized the synthetic methodologies of arsenic(III) halides (AsX3; X = Br, I) and examined the difference of their physical properties such as solubility to organic solvent and reactivity
砷配体在配位化学中引起了相当大的关注。卤化砷(III)是制备单齿砷配体的最重要原料。在这项工作中,我们优化了卤化砷(III)(AsX 3; X = Br,I)的合成方法,并研究了其物理性质的差异,例如对有机溶剂的溶解度和对亲核试剂的反应性。此外,用获得的AsX 3制备了多种单齿砷配体。最后,将所获得的单齿砷配体用于与卟啉的反应体系中的无铜Sonogashira交叉偶联反应。结果表明,单齿砷配体比三苯基膦具有更高的催化活性,这是由于砷和磷原子之间的孤对电子特性不同。

The Fourier transform (FT)-Raman and infrared (IR) spectra of triphenyl-, perdeuterated triphenyl-, tris(2-methylphenyl)-, tris(3-methylphenyl)-, tris(2,4, 6-trimethylphenyl)-, tris(2-methoxyphenyl)-, tris(3 -methoxyphenyl)-, tris(3-fluorophenyl)- and tris(4-fluorophenyl)-arsine, -stibine and -bismuthine were measured in the range 3600-100 cm(-1). A normal coordinate analysis was performed for all substances using a modified valence force field. This leads to an unique force field for these compounds, where only the metal depending force constants vary noticeably. It was also possible to find a relationship between the chemical nature and the position of the different substituent and the metal-carbon stretching force constant. For all substances H-1-NMR,C-13-NMR and MS data were also given. (C) 1997 Elsevier Science B.V.
