    Synthesis of C2-Symmetric Diphosphormonoamidites and Their Use as Ligands in Rh-Catalyzed Hydroformylation: Relationships between Activity and Hydrolysis Stability
    (Weinheim : Wiley-VCH-Verl., 2017-1-23) Morales Torres, Galina; Behrens, Stephan; Michalik, Dirk; Selent, Detlef; Spannenberg, Anke; Lühr, Susan; Dyballa, Katrin Marie; Franke, Robert; Börner, Armin
    A series of diphosphoramidites has been synthetized with a piperazine, homopiperazine, and an acyclic 1,2-diamine unit in the backbone. New compounds were tested alongside related N-acyl phosphoramidites as ligands in the Rh-catalyzed hydroformylation of n-octenes to investigate their influence on the activity and regioselectivity. A subsequent study of their hydrolysis stability revealed that the most stable ligands induced the highest activity in the catalytic reaction.
