The 1,4- and 1,2-addition of phosphites to α,β-unsaturated hydrazones was investigated. When silylated phosphites and trialkyl phosphites were compared, trialkyl phosphites gave better conversions and subsequently higher yields. A variety of hydrazones were evaluated as substrate in this reaction, which yield 3-phosphonyl-1-hydrazinoalkyl phosphonates.
探讨了膦酸酯对α,β-不饱和腙的1,4-和1,2-加成反应。对比了甲硅烷基化膦酸酯和三烷基膦酸酯的效果,结果表明三烷基膦酸酯的转化率更高,从而获得了更高的产率。在该反应中评估了多种腙作为底物,最终产物为3-膦酰基-1-肼基烷基膦酸酯。
