Ruthenacycles and Iridacycles as Transfer Hydrogenation Catalysts
Autor: Vincent Ritleng, Johannes G. de Vries
Publikováno v: Molecules, Vol 26, Iss 13, p 4076 (2021)
In this review, we describe the synthesis and use in hydrogen transfer reactions of ruthenacycles and iridacycles. The review limits itself to metallacycles where a ligand is bound in bidentate fashion to either ruthenium or iridium via a carbon–me

Betti base derived P-stereogenic phosphine-diamidophosphite ligands with a single atom spacer and their application in asymmetric catalysis
Autor: Soumyadeep Chakrabortty, Katharina Konieczny, Paul C. J. Kamer, Anke Spannenberg, Johannes G. de Vries, Bernd H Mueller
Publikováno v: Catalysis Science & Technology. 12:1392-1399
A set of hybrid P-stereogenic phosphine-diamidophosphite ligands based on the Betti base backbone has been synthesized. The ligands possess five chiral centers including the P-chirality in both the phosphorus atoms. The synthesis involves the incorpo
