一般說明
正丁基锂(n-BuLi)是有机锂试剂,在无机合成中广泛用作强碱(超强碱),用于各种化学中间体的制备。也作为试剂,用于锂卤交换反应和锂-金属的金属交换反应。正丁基锂可锂化碳酸类化合物(carbon acids)。
應用
正丁基锂(2.0 M环己烷溶液)可用作:
- 聚合引发剂,通过阴离子聚合苯乙烯合成聚苯乙烯。
- 强碱,用于非对映选择性烷基化反应。
- 作为试剂与苯甲醛类和二(1H-吡咯-1-yl)四氯化锆反应合成2-苯甲酰基吡咯。

Two-dimensional (2D) semiconducting monolayer transition metal dichalcogenides (TMDCs) have stimulated lots of interest because they are direct bandgap materials that have reasonably good mobility values. However, contact between most metals and semiconducting TMDCs like 2H phase WSe2 are highly resistive
