Formula: C38H34N2O4P2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine, is researched, Molecular C38H34N2O4P2, CAS is 221012-82-4, about Asymmetric hydroformylation of styrene catalyzed by P-Phos-Rh complexes [P-Phos = 4,4′,6,6′-tetramethoxy-2,2′-bis(diphenylphosphino)-1,1′-bipyridine].
Rh complex was prepared by complexation of (R)-P-Phos with the available Rh precursor and used for the asym. hydroformylation of styrene. The effects of total pressure, temperature, and the ratio of phosphine/Rh on catalytic activity, chemo- and enantioselectivity were discussed. (R)-P-Phos-Rh showed higher activity and regioselectivity and the enantioselectivity was as much as that catalyzed by -BINAP-Rh (BINAP = 2,2′-di(diphenylphosphino)-1,1′-bipyridine) in the in situ asym. hydroformylation of styrene.
