  大芳基取代基通过对位官能化对二膦和磷烯烃中低配位磷原子的电子效应

  摘要：

  大芳基取代基对二膦和磷烯烃中低配位磷原子的电子效应已通过取代基的对位官能化进行了研究。制备了在对位带有给电子或吸电子基团的大块溴苯作为取代基的前体，并将其中的一些用于制备相应的二膦和带有低配位磷原子的芴基（苯基）膦. UV-vis光谱和3 1 PNMR化学位移表明系统中对位取代基的电子扰动。这些观察结果可归因于大芳基取代基对低配位磷原子的孤对电子特性引起的影响。

  Preparation and Properties of Phosphaethynes Bearing Bulky Aryl Groups with Electron-Donating Substituents at the Para Position

  摘要：

  Phosphaethynes bearing a 2,6-di-tert-butyl-4-(dimethylamino)phenyl, 2,6-di-tert-butyl-4-methoxyphenyl, or 2,6-di-tert-butylphenyl group were prepared. A P-31 NMR spectroscopic investigation of the chemical shifts indicated that electron-donating groups at the para position cause shifts to a higher field. Bathochromic shifts caused by the electron-donating groups were apparently observed in UV-vis spectra. The structure of 2-[2,6-di-tert-butyl-4-(dimethylamino)phenyl]-1-phosphaethyne was analyzed by X-ray crystallography.

  The electronic effects of bulky aryl substituents on low coordinated phosphorus atom(s) in diphosphenes and phosphaalkenes have been examined by means of functionalization at the para position of the substituents. Bulky bromobenzenes bearing an electron-donating or electron-withdrawing group at the para position were prepared as precursors of the substituents and some of them were applied to preparations
