Abstract
Palladium(II) complexes of the TPA family (TPA − tris(2-pyridylmethyl)amine) have recently emerged as efficient catalysts of highly 3°-regioselective hydroxylation and chemoselective 2°-ketonization of aliphatic C–H groups with peroxycarboxylic acids. Herewith, we present a novel facet of the catalytic reactivity of such complexes that have been shown to mediate highly efficient (at as low as 0.6 mol. % catalyst loadings) and selective trifluoroethoxylation of organic substrates at benzylic C–H groups, affording the corresponding trifluoroethoxy ethers in up to 73 % isolated yield. The developed synthetic protocol allows for diastereoselective trifluoroethoxylation of complex molecules of natural origin (steroids, terpenoids).
期刊介绍:
The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes.
The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods.
The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
