A mild and efficient method for the synthesis of allenes through selective copper-catalyzed hydride addition to propargylic chlorides using commercially available diisobutylaluminum hydride has been developed. This transformation, which is promoted by a readily accessible N-heterocyclic carbene–copper complex, provides a wide range of new and versatile functionalized allenes in good to excellent yields
已经开发了一种温和而有效的方法,该方法通过使用市售的二异丁基氢化铝,通过将铜催化的氢化物选择性加成到炔丙基氯化物中来合成丙二烯。N-杂环卡宾-铜配合物易于获得,促进了这种转变,提供了多种新型且用途广泛的功能化异戊烯,具有良好的收率和优异的收率,并具有较高的区域选择性和立体选择性。
