To further broaden the methods for the heterogeneous phase alkylation of CH acidic compounds, the dialkylation of diethyl ethoxycarbonylmethylphosphonate was studied in the presence of Cs2CO3 under microwave and solvent-free conditions. It was found that after repeating the alkylations by the addition of newer portions of the alkylating agent and the base on a few occasions, the dialkylation was quite
为了进一步拓宽 CH 酸性化合物的多相烷基化方法,在微波和无溶剂条件下,在 Cs2CO3 存在下研究了乙氧基羰基甲基膦酸二乙酯的二烷基化。发现在几次通过添加新部分的烷基化剂和碱重复烷基化之后,二烷基化非常有效。甚至可以合成具有不同烷基的二烷基衍生物。相转移催化剂的存在是有害的,因为它阻止了二烷基产物的形成。
