The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: [Ir(dtbbpy)(ppy)2]PF6( cas:676525-77-2 ) is researched.Product Details of 676525-77-2.Tlahuext-Aca, Adrian; Garza-Sanchez, R. Aleyda; Glorius, Frank published the article 《Multicomponent Oxyalkylation of Styrenes Enabled by Hydrogen-Bond-Assisted Photoinduced Electron Transfer》 about this compound( cas:676525-77-2 ) in Angewandte Chemie, International Edition. Keywords: multicomponent oxyalkylation styrene hydrogen bond assisted photoinduced electron transfer; acyloxy phthalimide iridium catalyzed condensation styrene photoinduced electron transfer; alkyl radicals; decarboxylation; hydrogen bonding; oxyalkylation; photoredox catalysis. Let’s learn more about this compound (cas:676525-77-2).
Herein, authors disclose a strategy for the activation of N-(acyloxy)phthalimides towards photoinduced electron transfer through hydrogen bonding. This activation mode enables efficient access to C(sp3)-centered radicals upon decarboxylation from bench-stable and readily available substrates. Moreover, they demonstrate that the formed alkyl radicals can be successfully employed in a novel redox-neutral method for constructing sp3-sp3 bonds across styrene moieties that gives straightforward access to complex alc. and ether scaffolds.
As far as I know, this compound(676525-77-2)Product Details of 676525-77-2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
