过渡金属有机化合物在一定条件下,金属原子可在分子内发生迁移,进而实现新位点的官能团化,金属迁移反应中,迁移方向的有效控制一直是挑战性难题,一般来说,芳基钯物种相比烯基钯物种具有更高的热力学稳定性.因此,虽然烯基向芳基位置的1,4-钯迁移很早就被人熟知,但是其逆反应,一直没有被实现,中国科学院上海有机化学研究所林国强研究员、冯陈国副研究员及其合作者通过
Transition metal organic compounds under certain conditions, the metal atoms can occur within the molecule migration, and thus the new site functionalization, metal migration reaction, the effective control of the migration direction has been a challenging problem, in general, aryl palladium Species have higher thermodynamic stability than alkenyl palladium species. Therefore, although the 1,4-Pd transport of an alkenyl group to an aryl group has long been known, the reverse reaction has not been realized.
