In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Palladium/Lewis Acid Co-catalyzed Divergent Asymmetric Ring-Opening Reactions of Azabenzonorbornadienes with Alcohols, published in 2016-10-07, which mentions a compound: 503538-69-0, Name is (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole, Molecular C38H24F4O4P2, Safety of (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole.
By fine tuning the combinations of chiral palladium catalysts and Lewis acids, both the addnl. and reductive asym. ring-opening reactions of azabenzonorbornadienes with alcs. were accomplished with good chemoselectivity, regioselectivity, and enantioselectivity. It was proven that the reductive ring-opening products were generated through a transfer hydrogenation process with alcs. as hydrogen source.
In some applications, this compound(503538-69-0)Safety of (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
