Rh(2)(II)-carboxylate complexes were discovered to promote the selective migration of aminomethylenes in β,β-disubstituted styryl azides to form 2,3-disubstituted indoles. Mechanistic data are also presented that suggest that the migration occurs stepwise before diffusion of the iminium ion.
Rh(2)(II)-羧酸盐配合物被发现可促进β,β-二取代苯乙烯基叠氮化物中氨甲基的选择性迁移,形成 2,3-二取代吲哚。还提出了机理数据,表明迁移是分步进行的,然后才是亚铵离子的扩散。
