Pd/C-Catalyzed transfer hydrogenation of N–H indoles with trifluoroethanol and tetrahydroxydiboron as the hydrogen source

Under the guidance of hydrogenation of indoles and transfer hydrogenation with tetrahydroxydiboron, Pd/C catalyzed transfer hydrogenation of N–H indoles with trifluoroethanol and tetrahydroxydiborane as the hydrogen source has been developed.
