simple method for the preparation of 2- or 2,7-functional pyrenes from 1- or 1,6-substituted derivatives is reported. The synthesis involves the unexpected 1,2-phosphinyl migration in an AlCl3/NaCl melt. The structure of the product has been unambiguously confirmed by X-ray crystallography. We also demonstrated that further functionalization of pyrene through C–P bond activation is possible. These 2,7-positions
报道了一种由1-或1,6-取代的衍生物制备2-或2,7-官能pyr的简单方法。合成过程涉及AlCl 3 / NaCl熔体中意外的1,2-亚膦酰基迁移。通过X射线晶体学已明确证实了产物的结构。我们还证明了through通过C-P键活化的进一步功能化是可能的。否则,很难推导这2,7位。
