Application

Rh2(esp)2: An Exceptionally Efficient and Selective Catalyst for C-H Amination

Reagent for:
  • Preparation of α,β-unsaturated-γ-lactams via Rh-catalyzed C-H amination of allene carbamates, then Ru-catalyzed cyclocarbonylation
  • Palladium-catalyzed diamination
  • Preparation of functionalized bicyclic heterocyclic compounds by rhodium-catalyzed allene amidation and cyclization
  • Preparation of piperidine and pyrrolidine derivatives via copper-catalyzed intramolecular aminoacetoxylation of aminoolefins
  • C-H acyloxylation of arenes

  • Hypervalent iodine oxidant
Hypervalent iodine reagent used with the Rh2(esp)2 catalyst (662623) in the amination of C-H bonds.

Oxidative fragmentation of tertiary cyclopropanols with phenyliodine(III) dicarboxylates in aprotic solvents (dichloromethane, chloroform, toluene) produces mixed anhydrides. The fragmentation reaction is especially facile with phenyliodine(III) reagents bearing electron-withdrawing carboxylate ligands (trifluoroacetyl, 2,4,6-trichlorobenzoyl, 3-nitrobenzoyl), and affords 95-98% yields of the corresponding

Reaction methodology for intermolecular C-H amination of benzylic and 3 degrees C-H bonds is described. This process uses the starting alkane as the limiting reagent, gives optically pure tetrasubstituted amines through stereospecific insertion into enantiomeric 3 degrees centers, displays high
