Preparation of 2-Magnesiated 1,3,5-Triazines via an Iodine-Magnesium Exchange

[摘要]：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 ZnCl2). 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 optoelectronic properties.
