鋰類(lèi)化合物有哪些
鋰的烷基衍生物,是一種強(qiáng)路易斯堿,包括正丁基鋰、甲基鋰、苯基鋰等。烷基鋰能對(duì)羰基化合物進(jìn)行加成反應(yīng),還能對(duì)活潑氫進(jìn)行置換反應(yīng),以及鹵素-鋰交換反應(yīng),其反應(yīng)性能比一般格氏試劑要廣泛而且多樣化。
1、不使用過(guò)渡金屬的偶聯(lián)反應(yīng)。
J. Am. Chem. Soc., 2011, 133 (12), 4243–42
2、高收率的不對(duì)稱去質(zhì)子化反應(yīng)。
J. Am. Chem. Soc., 2010, 132 (21), 7260–7261
