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 Iridium-Catalyzed Asymmetric Allylic Amination Reactions with N-Aryl Phosphoramidite Ligands, published in 2016-08-08, which mentions a compound: 415918-91-1, mainly applied to chiral allyl iridium binaphthol phosphoramidite metallacycle preparation crystal structure; crystal structure chiral allyl iridium binaphthol phosphoramidite metallacycle; mol structure chiral allyl iridium binaphthol phosphoramidite metallacycle; iridium catalyzed asym allylic amination phosphoramidite ligand, Safety of (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine.
N-aryl phosphoramidite ligands were synthesized, and the Ir complexes derived from these novel ligands were proven to be efficient catalysts for asym. intermol. allylic amination reactions. This C-N bond forming process readily accommodates a diverse range of amines and allylic carbonates, especially for the previously challenging ortho-substituted cinnamyl substrates. Also, isolation and characterization of the corresponding (π-allyl)-Ir complex K1 reveal that the active iridacycle is generated through a C(sp2)-H bond insertion of tetrahydroquinoline of the ligand.
The article 《Iridium-Catalyzed Asymmetric Allylic Amination Reactions with N-Aryl Phosphoramidite Ligands》 also mentions many details about this compound(415918-91-1)Safety of (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine, you can pay attention to it, because details determine success or failure
