phosphinates and some H-phosphonate diesters is promoted by the base DBU. Only more reactive alkyl halides react in preparatively useful yields. However, the method provides easy access to important H-phosphinate building blocks, without the need for a protecting group strategy or metal catalysts. The reaction is conveniently conducted at, or below, room temperature. The preparation of methyl-H-phosphinate
DBU碱促进烷基次膦酸酯和一些H-膦酸酯二酯的烷基化。只有更多的反应性烷基卤化物以制备有用的产率反应。但是,该方法无需重要的保护基策略或金属催化剂即可轻松获得重要的H-次膦酸酯结构单元。该反应方便地在室温或低于室温下进行。甲基的制备ħ -phosphinate酯是特别令人感兴趣的,因为它避免了以往更普遍使用methyldichlorophosphine MePCl的2。
