Abstract

The photochemical reaction of the amine substrates does not require any metal catalyst and is effective in the presence of 9-mesityl-10-methylacridinium tetrafluoroborate and thiophenol as a hydrogen donor.

4. ChemInform Abstract: Quasi-Nature Catalysis: Rhodium-Catalyzed C-C Bond Formation in Air and Water

Abstract

Transition-metal catalysis is out-grown from dry-boxes where the use of inert gas atmosphere and the exclusion of moisture have been essential. Such a restriction undoubted- ly imposes limitations in the application of these reactions in organic synthesis and in the recycling of the catalysts. This article discusses some recent advances of rhodium-catalyzed carbon-carbon bond formations under the natural conditions of air and water.
