Optimum conditions for the solid–liquid phase alkylation of methylenebis(diphenylphosphine oxide) (MBDPPO) and ethyl cyanomethylphosphonate (ECMP) were explored studying the role of phase transfer catalysis and microwave (MW) irradiation, as well as the effect of the cation of the alkali carbonate. It was found that the alkylation of MBDPPO may be best accomplished in acetonitrile, in the presence
探讨了亚甲基双(二苯基氧化膦)(MBDPPO)和氰甲基膦酸乙酯(ECMP)固液相烷基化的最佳条件,研究了相转移催化和微波(MW)辐射的作用,以及阳离子的影响碱金属碳酸盐。发现 MBDPPO 的烷基化在乙腈中,在季铵盐和 Cs2CO3 的存在下可以最好地完成,而 ECMP 在没有催化剂和溶剂的情况下使用 K2CO3 进行烷基化。MW 辐照在这两种情况下都是有益的。在 ECMP 的烷基化过程中,还鉴定了来自二乙酯醇解的副产物。© 2011 Wiley Periodicals, Inc. 杂原子化学 22:174–179, 2011; 在 wileyonlinelibrary.com 上在线查看这篇文章。DOI 10.1002/hc.20673
