Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1265884-98-7, is researched, Molecular C34H22NO2P, about Study of Intermediates in Iridium-(Phosphoramidite,Olefin)-Catalyzed Enantioselective Allylic Substitution, the main research direction is intermediate iridiumphosphoramiditeolefincatalyzed enantioselective Allylic substitution crystallog.Reference of 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine.
Exptl. mechanistic studies of iridium-catalyzed, enantioselective allylic substitution enabled by (phosphoramidite,olefin) ligands are reported. (η2-Allylic alc.)iridium(I) and (η3-allyl)iridium(III) complexes were synthesized and characterized by NMR spectroscopy as well as x-ray crystallog. The substrate complexes are catalytically and kinetically competent to be intermediates in allylic substitutions of branched, racemic allylic alcs. with various nucleophiles. The authors have identified an off-cycle pathway involving reversible binding of mol. oxygen to iridium, which contributes to the air tolerance of the catalyst system.
