Highly substituted benzene derivatives have been easily prepared in a regioselective way from readily available 1,3-hexadien-5-ynes through a gold(I)-catalyzed tandem reaction. The process involves an initial cyclization followed by a selective Wagner–Meerwein shift in which the migration preference seems to be determined by the ability to stabilize a positive charge.
高取代的苯衍生物很容易以区域选择性的方式从容易获得的1,3-己二烯-5-炔通过金(I)催化的串联反应制备。该过程涉及最初的环化,然后是选择性的Wagner-Meerwein转变,其中迁移偏好似乎由稳定正电荷的能力决定。
