  A concise method for synthesis of diaryl aryl- or alkylphosphonates

  摘要：

  A convenient method has been developed to synthesize diaryl arylphosphonates from triaryl phosphites, triethyl phosphite, and aromatic halides. The new method relies on the triethyl phosphite assisted nickel catalyzed Arbuzov reaction and can be applied to synthesize certain diaryl alkylphosphonates without catalysts. (c) 2005 Elsevier Ltd.

• A new synthesis of π-electron conjugated phosphonates and phosphonic bis(diethylamides) and their SHG activities

  A series of vinylic and arylic phosphonates and phosphonic bis(diethylamides) were prepared by copper promoted substitution of the corresponding bromides. These π-electron conjugated phosphonates and phosphonic bis(diethylamides) were investigated to elucidate their optical and second harmonic generation (SHG) properties; it was found that diphenyl 2-(4-dimethylaminophenyl)ethenylphosphonate exhibited strong SHG activity, the efficiency being 13 times greater than that of urea.

  通过铜催化的相应溴化物的取代反应，制备了一系列乙烯基和芳基膦酸盐及双（二乙基酰胺）膦酸。研究了这些共轭的磷酸盐和双（二乙基酰胺）膦酸的光学性质和二次谐波产生（SHG）特性；发现二苯基2-（4-二甲氨基苯基）乙烯基膦酸盐具有强烈的SHG活性，效率比尿素高13倍。

  Michaelis–Arbuzov reaction of carboxylic acids and triaryl phosphites for preparing aryl phosphonates under anhydride-free conditions has been reported. In this context, triaryl phosphites serve as both reagents for activating the carboxylic acids and substrates for the reaction. There have been no reports to date of efficient and direct methods for the in situ activation of carboxylic acids using triaryl phosphites

  据报道，在无酸酐条件下，通过钯催化的羧酸和亚磷酸三芳基酯的脱羰米氏-阿布佐夫反应制备膦酸芳基酯。在本文中，亚磷酸三芳基酯既充当用于活化羧酸的试剂又充当反应的底物。迄今为止，还没有关于使用亚磷酸三芳基酯原位活化羧酸的有效且直接的方法的报道。与已知方法相比，该反应避免了有机卤化物的使用，并且对于由亚磷酸三芳基酯和羧酸合成各种膦酸芳基酯具有优异的官能团耐受性。该反应具有可扩展性，适用于合成具有生物活性片段的芳基膦酸酯。
