In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Assessing the Activity of Lewis Bases Organocatalysts in Halonium-Induced Carbocyclization Reactions, published in 2018-06-30, which mentions a compound: 415918-91-1, mainly applied to Lewis base organocatalyst halonium carbocyclization alkynylstyrene cinnamylaniline; phosphine phosphorus chalcogenide halosuccinimide catalyzed carbocyclization alkynylstyrene; halonium induced carbocyclization alkynylstyrene cinnamylaniline, Synthetic Route of C36H30NO2P.
Lewis bases were evaluated as catalysts for halocarbocyclization reactions of alkynylstyrenes and a cinnamylaniline derivative Phosphines and phosphorus chalcogenides exhibited high activity for the conversion of alkynylstyrenes in the presence of N-halosuccinimides with up to a 30-fold increase of the initial reaction rate with respect to the background reaction. Phosphorus sulfides and selenides showed the best catalytic activity for the iodocarbocyclization of a cinnamylaniline derivative in the presence of diiodohydantoin. An asym. variant of the iodocarbocyclization reaction of an alkynylstyrene using a chiral phosphorus selenide resulted in a modest enantioselectivity.
Although many compounds look similar to this compound(415918-91-1)Synthetic Route of C36H30NO2P, numerous studies have shown that this compound(SMILES:C[C@@H](N(P1OC2=CC=C3C=CC=CC3=C2C4=C5C=CC=CC5=CC=C4O1)[C@@H](C6=CC=CC=C6)C)C7=CC=CC=C7), has unique advantages.
