aryl, etc.), were synthesized by means of a three-component reaction between the elemental selenium and the corresponding vinyl ether and secondary phosphine. The reaction proceeds readily in 1,4-dioxane at 90 ˚C for 1-1.5 hours and gives the phosphinodiselenoic esters quantitatively and in an entirely atom-economic manner. The reaction proceeds through electrophilic addition to the electron-rich
借助于三组分合成了一个含有硒缩醛部分R 2 2 P(= Se)SeCH(Me)OR 1(R 1,R 2=烷基,芳基等)的膦酸二亚硒酸酯系列。元素硒与相应的乙烯基醚和仲膦之间的反应。该反应可在90°C下于1,4-二恶烷中轻松进行1-1.5小时,并以完全原子经济的方式定量获得膦二亚硒酸酯。反应通过亲电加成到原位生成的膦二硒酸的富电子双键上进行。 膦-多组分反应-磷-硒-膦二硒酸酯
