The first uncatalyzed hydrophosphinations of propargylic amines and alcohols with phosphine– borane complexes are described. The reactions proceed at ambient temperature or below without the use of protecting groups or the need to handle pyrophoric secondary phosphines, furnishing air-stable phosphineborane–amines and alcohols in good yields. Utilization of chiral propargylic substrates and unsymmetrical
描述了炔膦胺和醇与膦-硼烷配合物的首次未催化加氢磷酸化。反应在室温或更低的温度下进行,无需使用保护基或无需处理发火性仲膦,即可提供稳定的空气稳定的膦硼烷-胺和醇。手性炔丙基底物和不对称仲膦硼烷的利用导致可通过分级结晶或色谱法分离的非对映体P-手性产物。详细介绍了这些新的P–X物质在不对称催化中的初步应用。
