[reaction: see text] Air (oxygen) induces the addition of secondary phosphine oxides and H-phosphinates to alkenes to selectively produce the corresponding anti-Markovnikov adducts in good to high yields. Mechanistic studies show that the addition probably proceeds via a radical chain mechanism.
[反应:见正文] 空气(氧气)促使二级氧化膦和次膦酸酯与烯烃加成,以良好至高产率选择性地生成相应的反马氏加成产物。机理研究表明,该加成反应可能通过自由基链机理进行。
