Recommanded Product: trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium, is researched, Molecular C46H46O4P2Pd2, CAS is 172418-32-5, about Heck arylation of α,β-unsaturated aldehydes. Author is Nejjar, A.; Pinel, C.; Djakovitch, L..
The Heck arylation of α,β-unsaturated aldehydes is strongly dependent on the catalyst, the solvent and the base. Optimized conditions yielded either selectively cinnamyl derivatives (83%) or double arylation products (88% based on aryl conversion). A new α-arylation of β,β-disubstituted acrolein is also realized.
