reaction conditions for the preparation of pure aryl-H-phosphinate esters, originally developed by Sander and optimized by Petneházy, is reported. The influence of the reaction concentration has been investigated for the formation of phosphonite intermediates via direct addition of triethyl phosphite to the appropriate Grignard reagent. Subsequent hydrolysis of the phosphonites under acidic conditions gives
报道了由Sander最初开发并由Petneházy优化的制备纯芳基-H-次膦酸酯的反应条件的系统研究。通过将亚磷酸三乙酯直接添加到适当的格氏试剂中,研究了反应浓度对亚膦酸酯中间体形成的影响。亚膦酸酯随后在酸性条件下的水解以高产率和纯度得到各种芳基-H-次膦酸酯。 亚膦酸酯-次膦酸酯-芳基-H-次膦酸酯-亚磷酸三乙酯-水解-格氏试剂
