the reaction of bis(naphth-1,8-diyl-8-oxy)hydrophosphorane with an equimolar amount of terminal and internal olefins gave the corresponding alkylphosphoranes. In the reactions with styrene and methyl acrylate, 2:1 olefin–hydrophosphorane adducts were obtained as a minor product. The reactions with terminal olefins were entirely regioselective and more efficient than those with internal olefins. In
在 1,1'-偶氮双(环己烷甲腈)(ACHCN)存在下,双(萘-1,8-二基-8-氧基)氢正膦与等摩尔量的末端和内烯烃反应得到相应的烷基正膦。在与苯乙烯和丙烯酸甲酯的反应中,得到 2:1 的烯烃-氢正膦加合物作为次要产物。与末端烯烃的反应是完全区域选择性的,并且比与内烯烃的反应更有效。在没有 ACHCN 的情况下,氢正膦与端烯烃和内烯烃的自由基加成反应也可以缓慢进行。© 2011 Wiley Periodicals, Inc. 杂原子化学 22:538–544, 2011; 在 wileyonlinelibrary.com 上在线查看这篇文章。DOI 10.1002/hc.20719
