On April 1, 2011, Joshi, S. N.; Vyas, S. M.; Duffel, M. W.; Parkin, S.; Lehmler, H.-J. published an article.Recommanded Product: 1,5-Dichloro-3-methoxy-2-nitrobenzene The title of the article was Synthesis of sterically hindered polychlorinated biphenyl derivatives. And the article contained the following:
A series of sterically hindered (methoxylated) polychlorinated biphenyl derivatives were synthesized using the Suzuki and the Ullmann coupling reactions. The Suzuki coupling with Pd(dba)2/2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (DPDB) gave better yields (65-98%) compared to the classic Ullmann coupling reaction (20-38%). Despite the reactive catalyst system, no significant coupling with aromatic chlorine substituents was observed Crystal structure anal. of four PCB derivatives revealed solid state dihedral angles ranging from 69.7° to 81.0°, which indicates that these highly ortho-substituted PCB derivatives have some conformational flexibility. The experimental process involved the reaction of 1,5-Dichloro-3-methoxy-2-nitrobenzene(cas: 74672-01-8).Recommanded Product: 1,5-Dichloro-3-methoxy-2-nitrobenzene
