Borane adducts with selected N,N-dialkylanilines have been prepared and examined as hydroborating agents. The adduct H3B:NPhPri2 is a solid, considered less desirable than liquid adducts as hydroborating agents. Fortunately, the adducts H3B:NPhBuiMe, H3B:NPhPriMe, H3B:NPhPriEt, and H3B:NPhPriPrn are liquids above 0 °C, hydroborating 1-octene in tetrahydrofuran in less than 1 h at room temperature.
已经制备了具有选择的N,N-二烷基苯胺的硼烷加合物,并作为硼氢化剂进行了研究。加合物H 3 B:NPhPr i2是固体,被认为不如液体加合物作为氢硼酸酯化剂是合乎需要的。幸运的是,加合物H 3 B:NPhBu i我,H 3 B:NPhPr i我,H 3 B:NPhPr iEt和H 3 B:NPhPr i镨ñ是高于0°C的液体,在室温下少于1小时内在四氢呋喃中进行硼氢化1-辛烯。描述了通过硼烷-N,N-二异丙基苯胺加合物的热离解或通过2.00 M硼氢化钠在三甘醇二甲醚中的溶液与5.40 M的三氟化硼在三甘醇二甲醚溶液中的反应来定量生成气态乙硼烷的简便方法。
