关于正丁基锂的使用问题？ 我要做一个实验要用到 正丁基锂 拔氢，但是文献上说直接加入正丁基锂，之后在60℃搅拌3小时，之后再冷却到-78℃。 我担心不会出现什么问题吧？正丁基锂不是一般都在-78℃加入、反应吗？ 请高手解答疑惑！ 附原文： Naphthalene (0.77 g, 6 mmol) was stirred with 9.2mL of hexane containing 24 mmol butyllithium and 3.6 mL (12 mmol) of TMEDA at 60°C for 3 hours.The resulting dark brown suspension of the lithio derivatives was allowed to cool to -78°C and was diluted with 25 mL of THF. Resublimed sulfur (1.6g, 50 mmol) was added to the suspension. The resulting orange mixture was warmed to 25°C and allowed to stir for 12 hours. It was then washed with water and the organic layer was separated and dried over anhydrous MgSO4. 摘自：Heteroatom Chemistry. Volume 5, Number 2, 1994查看更多4个回答 . 1人已关注
