A method has been developed for the facile Cu(II)-catalyzed protoboration of monosubstituted allenes in aqueous media under atmospheric conditions. The reaction occurs site selectively, favoring internal alkene protoboration to afford 1,1-disubstituted vinylboronic acid derivatives (up to 93 : 7) with modest to good yields. The method has been applied to a variety of phenylallene derivatives as well
已经开发了一种在大气条件下在水性介质中容易地用Cu(II)催化单取代的烯基的原硼氢化的方法。该反应选择性地发生,有利于内部烯烃的原硼烷基化,以适度到良好的产率得到1,1-二取代的乙烯基硼酸衍生物(至多93∶7)。该方法已应用于多种苯丙二烯衍生物以及烷基取代的丙二烯。
