Category: chiral-phosphine-ligands. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium, is researched, Molecular C46H46O4P2Pd2, CAS is 172418-32-5, about Highly selective palladium-catalyzed Heck reactions of aryl bromides with cycloalkenes. Author is Hartung, Christian G.; Koehler, Klaus; Beller, Matthias.
The influence of palladium catalysts and reaction conditions on the selectivity of Heck reactions of aryl bromides ArBr (Ar = 4-AcC6H4, 3-F3CC6H4, Ph, 4-MeOC6H4) with cyclohexene and cyclopentene has been investigated. The addition of DMSO as a co-solvent leads to improved selectivities of nonconjugated aryl olefins. High selectivities for conjugated arylcyclopentenes was obtained with the catalytic system N,N-dimethylacetamide/Na2CO3/Pd2(dba)3·dba/PCy3.
As far as I know, this compound(172418-32-5)Category: chiral-phosphine-ligands can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
