The research focuses on the synthesis and oxidation of chiral rhenium phosphine methyl complexes, with the goal of finding radical cations with enhanced kinetic stabilities. The study involves the reactions of racemic [(η5-C5Me5)Re(NO)(NCCH3)(CO)]+ BF4? with various phosphines, leading to the formation of phosphine carbonyl complexes [(η5-C5Me5)Re(NO)(PR3)(CO)]+ BF4? (5a–5f+ BF4?). These complexes are then reduced with LiEt3BH and BH3·THF to yield the phosphine methyl complexes (η5-C5Me5)Re(NO)(PR3)(CH3) (2a–2f). The synthesized compounds are analyzed using cyclic voltammetry, which reveals chemically reversible one-electron oxidations that are thermodynamically more favorable than the parent complex 2a. The radical cations generated are characterized using IR and ESR spectra, but attempts to isolate pure salts of these radicals fail due to their lability. The experiments also include a reaction with TCNE, leading to the formation of a new complex that is crystallographically characterized. The research involves a variety of analytical techniques, including NMR, IR, and mass spectrometry, to characterize the synthesized complexes and monitor the reactions.
The research focuses on the development and application of C3-symmetric proline-functionalized organocatalysts for enantioselective Michael addition reactions. The purpose of this study was to design catalysts with higher symmetry to reduce the number of reaction pathways and enhance selectivity in asymmetric synthesis. The researchers synthesized a series of C3-symmetric catalysts based on 1,3,5-triethylbenzene and evaluated their performance in the Michael addition of carbonyl compounds to β-nitrostyrenes. The catalysts were synthesized from Boc-protected L-proline and various substituted amines, and the key chemicals used in the process included ethyl chloroformate, trifluoroacetic acid (TFA), and borane-tetrahydrofuran complex (BH3·SMe2). The study concluded that the C3-symmetric catalyst 4, which allowed for conformational flexibility, was highly effective for the Michael addition reactions, leading to products with high diastereo- and enantioselectivities. This work demonstrates the potential of C3-symmetric catalysts in organocatalysis and their ability to control molecular order in enantioselective reactions.
