2,2-Diethoxyvinyllithium can be readily generated from 2-bromo-1,1-diethoxyethylene by treatment with butyllithium. When dissolved in tetrahydrofuran, it can be stored at −25 °C for hours, but decomposes rapidly at 0 °C.
通过用丁基
锂处理,可以容易地从2-
溴-
1,1-二乙氧基乙烯生成2,2-二乙氧基
乙烯基锂。溶于
四氢呋喃后,可在-25°C下保存数小时,但在0°C下会迅速分解。
