PROCEDURE

实验过程

5 ml aqueous solution of 392 mg (1.5 mmol) barium nitrate was added dropwise to 7.5 ml aqueous solution of 1 g (2.85 mmol) sodium (o-ethyl 3,5-di-tert-butyl-4-hydroxybenzylphosphonate) (phosphorus compound C described above) at room temperature under stirring. After the mixture was stirred for 1 hour, the precipitates were separated by filtration, washed with water and dried to give barium bis(o-ethyl 3,5-di-tert-butyl-4-hydroxybenzylphosphonate), 508 mg (45%).
