Chemical Research Letters, May 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. , Computed Properties of https://www.ambeed.com/products/6165-69-1.html, 6165-69-1, Name is 3-Thiopheneboronic acid, molecular formula is C4H5BO2S, belongs to naphthyridine compound. In a document, author is Daw, Prosenjit, introduce the new discover.
Cyclometalation on the substituted imidazo[1,2-a][1,8]naphthyridine platform involves either the C-3-aryl or C-4′-aryl ortho carbon and the imidazo nitrogen N-3′. The higher donor strength of the imidazo nitrogen in comparison to that of the naphthyridine nitrogen aids regioselective orthometalation at the C-3/C-4′-aryl ring with Cp*Ir-III (Cp* = eta(5)-pentamethylcyclopentadienyl). A longer reaction time led to double cyclometalations at C-3-aryl and imidazo C-5′-H, creating six- and five-membered metallacycles on a single skeleton. Mixed-metal Ir/Sn compounds are accessed by insertion of SnCl2 into the Ir-Cl bond. Pd(OAc)(2) afforded an acetate-bridged dinuclear ortho-metalated product involving the C-3-aryl unit. Metalation at the imidazo carbon (C-5′) was achieved via an oxidative route in the reaction of the bromo derivative with the Pd(0) precursor Pd-2(dba)(3) (dba = dibenzylideneacetone). Regioselective C-H/Br activation on a rigid and planar imidazonaphthyridine platform is described in this work.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. I hope my blog about 6165-69-1 is helpful to your research. Computed Properties of https://www.ambeed.com/products/6165-69-1.html.
