官能化的碘-和二碘-1,3,5-三嗪衍生物容易在低温下与BuMgCl、sBuMgCl或OctMgBr进行I/Mg交换,得到2-镁化和2-锌化的1,3,5-三嗪(在与ZnCl(2)进行金属交换之后)。这种方法也提供了一个方便的获得二镁化三嗪。此外,它允许制备官能化的1,3,5-三嗪基二聚体和三聚体,感兴趣的是它们的光电性能。
Functionalized iodo- and diiodo-1,3,5-triazine derivatives readily undergo an I/Mg exchange with BuMgCl, sBuMgCl, or OctMgBr at low temperatures furnishing 2-magnesiated and 2-zincated 1,3,5-triazines (after transmetalation with ZnCl(2)). This method also offers a convenient access to dimagnesiated triazines. Furthermore, it allows the preparation of functionalized 1,3,5-triazinyl dimers and trimers, interesting for their opto-electronic properties.
