Kashima, Kenichi; Ishii, Masahiro; Tanaka, Ken published the artcile< Synthesis of Pyridylphosphonates by Rhodium-Catalyzed [2+2+2] Cycloaddition of 1,6- and 1,7-Diynes with Diethyl Phosphorocyanidate>, Quality Control of 139139-86-9, the main research area is diyne cycloaddition enantioselective phosphorocyanidate preparation pyridylphosphonate fluorescence.
The convenient and atom-economical synthesis of substituted bicyclic pyridylphosphonates was achieved by the cationic Rh(I)/H8-binap-complex-catalyzed [2+2+2] cycloaddition of 1,6- and 1,7-diynes with di-Et phosphorocyanidate. These reactions may proceed via an azarhodacyclopentadiene intermediate in addition to the rhodacyclopentadiene intermediate.
European Journal of Organic Chemistry published new progress about Alkadiynes Role: RCT (Reactant), RACT (Reactant or Reagent). 139139-86-9 belongs to class chiral-phosphine-ligands, and the molecular formula is C44H40P2, Quality Control of 139139-86-9.
