Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 172418-32-5, is researched, SMILESS is CC1=C([P]2([Pd+2]3([CH2-]C4=C2C=CC=C4)[O-]/C(C)=O[Pd+2]5([O-]/C(C)=O3)[P](C6=C(C)C=CC=C6)(C7=C([CH2-]5)C=CC=C7)C8=C(C)C=CC=C8)C9=C(C)C=CC=C9)C=CC=C1, Molecular C46H46O4P2Pd2Journal, Tetrahedron Letters called Efficient and high turnover homocoupling reaction of aryl iodide by the use of palladacycle catalyst. A convenient way to prepare poly-p-phenylene, Author is Luo, Fen-Tair; Jeevanandam, Arumugasamy; Basu, Manas Kumar, the main research direction is homocoupling aryl iodide palladacycle catalyst; biaryl preparation; polyphenylene preparation.SDS of cas: 172418-32-5.
Monoiodoarenes undergo reductive coupling to produce biaryls in high yields in the presence of less than 0.1 mol % of palladacycle and N,N-diisopropylethylamine in DMF at 100°C. Under similar reaction conditions, p-diiodobenzene produces poly-p-phenylene in greater than 85% isolated yields.
This compound(trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium)SDS of cas: 172418-32-5 was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
