When tris(trimethylsilyl) phosphite (1) was treated with aldehydes, ketones, or α,β-unsaturated aldehydes at room temperature, the 1,2-adducts were obtained in high yields (75–94%). On the other hand, when α,β-unsaturated ketones or ethyl crotonate was used, the 1,4-adducts were obtained in high yields (71–84%). The silylated products were smoothly hydrolyzed to the corresponding phosphonates in almost
当亚磷酸三(三甲基甲硅烷基)酯 (1) 在室温下用醛、酮或 α,β-不饱和醛处理时,1,2- 加合物以高产率 (75-94%) 获得。另一方面,当使用 α,β-不饱和酮或巴豆酸乙酯时,1,4-加合物的产率很高(71-84%)。通过添加醇或水,硅烷化产物以几乎定量的产率顺利水解为相应的膦酸酯。
