New Bode catalysts for enantioselective annulations

Article Abstract:

Catalysis of enantioselective synthesis reactions using small organic molecules has become well-known due to its cost-efficiency, higher selectivity, and yield of lesser by-products compared to using chiral metal-ligand complexes. The development of novel, highly enantioselective reactions using imidazolium and triazolium salts is discussed.

Advances in homogeneous catalysis by gold complexes

Article Abstract:

Several research has been done on the use of gold salts and complexes in homogeneous catalysis and asymmetric catalysis. The homogeneous reactions can be categorized into alkyl bond formation through cycloisomerizations and the addition of R(sub 2)N-H across an alkenyl bond. The results of different studies on this topic are reviewed.

New developments in ruthenium-based catalysis

Article Abstract:

The syntheses of Neolyst M1 and M2 at multi-kilo scale and in high and consistent purity was optimized and scaled up by Umicore Precious Metals Chemistry. The homogeneous synthesis reactions involved using ruthenium-based complexes, and showed high stability and activity. The methods and results of the study are discussed.
