    标题:以磷酸钾为独特固体碱的双相体系合成三价磷酯
    摘要:三价磷酯的合成仍然是一个重要的关注领域,其中大部分再次针对金属催化反应的亚磷酸酯配体的合成.通常,它们是通过相应的氯化磷与适当的醇在胺存在下酯化而获得的.在本文中,我们提出了一种合成三价磷酯的新方法,当磷酸钾作为一种独特的碱用于液-固体系时,文献中尚未提及.使用这种方法可以以非常好的收率 (65%-80%) 获得对称和不对称的亚磷酸酯.化合物通过31P NMR光谱表征.© 2008 Wiley Periodicals,Inc. 杂原子化学 19:360-364,2008; 在线发表于 Wiley Interscience (Www.Interscience.Wiley.Com).Doi 10.1002/hc.

    标题:Synthesis of organic phosphate-phosphonates
    发明人：HARDY THOMAS A
    权利人:STAUFFER CHEMICAL CO
    摘要:A process for the preparation of organic phosphate-phosphonates comprises the steps of reacting an organic acylating agent with an organophosphite triester to form an intermediate followed by reacting the intermediate with an organophosphite diester. n Typically benzoyl chloride is the acylating agent, triethyl phosphite and bis (β-chloroethyl) phosphite the sequential reactants, and the second step is carried out in the presence of a catalytic amount of a tertiary amine. A solvent such as methylene dichloride may be employed. n Organic phosphate-phosphonates are useful as flame retardants, especially in urethane foams.

    摘要:The preparation of tris (2-chloroethyl) phosphite (TCEP) is carried out utilizing simultaneous additions of phosphorus trichloride and ethylene oxide to a heel of preformed TCEP. TCEP is useful as a high-pressure lubricant additive, an antioxidant, a flameproofing agent, or an org. synthesis intermediate.
