Lutter, Ferdinand H.; Grokenberger, Lucie; Spiess, Philipp; Hammann, Jeffrey M.; Karaghiosoff, Konstantin; Knochel, Paul published the article 《Cobalt-Catalyzed Cross-Coupling of Functionalized Alkylzinc Reagents with (Hetero)Aryl Halides》. Keywords: alkyl hetero aryl compound preparation; alkylzinc reagent hetero aryl halide cross coupling cobalt catalyst; alkylzinc reagents; catalysis; cobalt catalysis; cross-coupling; diastereoselectivity.They researched the compound: 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol( cas:35836-73-8 ).Application of 35836-73-8. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:35836-73-8) here.
A combination of 10% CoCl2 and 20% 2,2′-bipyridine ligands enables cross-coupling of functionalized primary and secondary alkylzinc reagents RZnY (R = 3-phenylpropyl, 3-(2,5-dimethyl-1H-pyrrol-1-yl)propyl, cyclopropyl, etc.; Y = Cl, Br) with various (hetero)aryl halides R1X (R1 = 5-cyanopyridin-2-yl, quinolin-2-yl, pyrimidin-2-yl, etc.; X = Cl, Br). Couplings with 1,3- and 1,4-substituted cycloalkylzinc reagents R2ZnI (R2 = 3-methylcyclohexyl, 4-(1H-pyrrol-1-yl)cyclohexyl, (4R,4aS,6R,8aR)-4,4a-dimethyl-6-(propan-2-yl)-decahydronaphthalen-2-yl, etc.) proceeded diastereoselectively leading to functionalized heterocycles R1R2 with high diastereoselectivities of up to 98:2. Furthermore, alkynyl bromides R3CCBr (R3 = Ph, tris(propan-2-yl)silyl) react with primary and secondary alkylzinc reagents RZnY (R = 2-(1,3-dioxan-2-yl)ethyl, 4-phenylcyclohexyl; Y = Cl, I) providing the alkylated alkynes RCCR3.
As far as I know, this compound(35836-73-8)Application of 35836-73-8 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
