Formula: C46H46O4P2Pd2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium, is researched, Molecular C46H46O4P2Pd2, CAS is 172418-32-5, about Rapid Formation of Triarylphosphines by Microwave-Assisted Transition Metal-Catalyzed C-P Cross-Coupling Reactions. Author is Stadler, Alexander; Kappe, C. Oliver.
Rapid, direct transition metal-catalyzed C-P(III) cross-coupling reactions were performed by microwave dielec. heating, employing diphenylphosphine and aryl halides/triflates as substrates. Depending on the specific aryl halide/triflate precursor, the highest yields were obtained using heterogeneous or homogeneous Pd or Ni catalysts in DMF or NMP in the presence of KOAc or DABCO as a base. E.g., treating 0.75 mmol PhI with 0.5 mmol KOAc and 2.0 mol % Pd/C in 1.0 mL DMF and then with 0.5 mmol Ph2PH in a sealed tube with microwave irradiation at 190° for 3 min gave 98% Ph3P. Other iodoarene substrates tested included 1-iodonaphthalene, o-IC6H4Br, m-IC6H4OMe, o-IC6H4NH2 and o-IC6H4CO2H, and afforded the corresponding aryl(diphenyl)phosphines in 26-86% yields.
This literature about this compound(172418-32-5)Formula: C46H46O4P2Pd2has given us a lot of inspiration, and I hope that the research on this compound(trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium) can be further advanced. Maybe we can get more compounds in a similar way.
