一般說明
正-丁基锂溶液(n-BuLi)是一种有机锂化合物,通常用作有机化学中的强碱。它还被用作各种锂基的锂源,例如氨基化锂、乙炔化锂和烷氧基锂。
應用
n-BuLi可作为强碱通过氮、氧、磷和碳酸的去质子化反应形成相应的锂盐。杂环化合物,如呋喃、噻吩、噁唑、吡咯等,可以使用 n-BuLi锂化 α 到环杂原子上。这些锂化盐与卤代烷原位反应,通过形成C-C键获得有用的有机化合物。 n-BuLi也是用于锂-卤素交换反应的有效试剂。通过使用 n-BuLi的原位反应还可合成许多其他有用试剂,如二异丙基氨基锂(LDA)和二苯基膦 。在双烯聚合反应中, n-BuLi用作引发剂。

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

A diamine-free protocol for the s-BuLi-mediated lithiation-trapping of N-Boc heterocycles has been developed. In the optimized procedure, lithiation is accomplished using s-BuLi in THF at -30 °C for only 5 or 10 min. Subsequent electrophilic trapping or transmetalation-Negishi coupling delivered
