Bis(trans-1-hexenyl)methylborane, prepared by the reaction of bis(trans-1-hexenyl)chloroborane with methyllithium, was treated with 2 molar equivalents of methylcopper(I) at −78 °C to give (5E,7E)-5,7-dodecadiene quantitatively. The result indicates the presence of trans-1-hexenylcopper(I) intermediate.
通过双(反式-1-己烯基)氯硼烷与甲基锂反应制备的双(反式-1-己烯基)甲基硼烷在-78°C下用2摩尔当量的甲基铜(I)处理得到(5E,7E) -5,7-十二碳二烯定量。结果表明存在反式-1-己烯基铜(I)中间体。
