Alcohol amination with ammonia catalyzed by an acridine-based ruthenium pincer complex: a mechanistic study

The mechanistic course of the amination of alcohols with ammonia catalyzed by a structurally modified congener of Milstein’s well-defined acridine-based PNP-pincer Ru complex has been investigated both experimentally and by DFT calculations. Several key Ru intermediates have been isolated and charac...

Description
Summary:The mechanistic course of the amination of alcohols with ammonia catalyzed by a structurally modified congener of Milstein’s well-defined acridine-based PNP-pincer Ru complex has been investigated both experimentally and by DFT calculations. Several key Ru intermediates have been isolated and characterized. The detailed analysis of a series of possible catalytic pathways (e.g., with and without metal-ligand cooperation, inner- and outer-sphere mechanisms) leads us to conclude that the most favorable pathway for this catalyst does not require metal-ligand cooperation.
