2,3-Dihydro-1H-inden-1-one derivatives were synthesized by a [5+2−2] decarbonylative cycloaddition of 1H-indene-1,2,3-trione and norbornene via rhodium(I) catalyzed direct carbon–carbon bond cleavage. A catalytic system combining [Rh(COD)Cl]2 (5.0 mol%) and rac-BINAP(10 mol%) ligand was optimal for these transformations. Various functional groups were tolerated under standard reaction conditions. Although
2,3-Dihydro-1 H -inden-1-one 衍生物是由 1 H -indene-1,2,3-trione 和降冰片烯通过铑( I ) 直接催化的 [5+2−2] 脱羰环加成反应合成的碳-碳键断裂。结合 [Rh(COD)Cl] 2 (5.0 mol%) 和rac -BINAP(10 mol%) 配体的催化体系是这些转化的最佳选择。在标准反应条件下可以耐受各种官能团。尽管在大多数情况下反应没有显示出区域选择性,但一些在 4 位具有-OMe、-CN 或强吸电子-CF 3基团的底物显示出高区域选择性。
