Application of 1265884-98-7

Application of 1265884-98-7. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine, is researched, Molecular C34H22NO2P, CAS is 1265884-98-7, about Allenylic Carbonates in Enantioselective Iridium-Catalyzed Alkylations.

An enantioconvergent C(sp3)-C(sp3) coupling between racemic allenylic electrophiles and alkylzinc reagents has been developed. An Ir/(phosphoramidite,olefin) catalyst provides access to highly enantioenriched allenylic substitution products (93-99% ee) with complete regiocontrol (>50:1 rr in all cases) over the undesired 1,3-dienes isomers which are obtained predominantly in the case of other metal catalysts. The synthetic utility of the products obtained was highlighted in a variety of stereoselective transition metal-catalyzed difunctionalization reactions. Furthermore, a combination of computational and exptl. studies supports a putative reaction mechanism wherein enantiodetermining C-C coupling occurs via nucleophilic attack on a highly planarized aryl butadienyl π-system that is coordinated to the Ir center in an η2-fashion.

This literature about this compound(1265884-98-7)Application of 1265884-98-7has given us a lot of inspiration, and I hope that the research on this compound(5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine) can be further advanced. Maybe we can get more compounds in a similar way.
