Herein, authors prepared two terpyridine-containing Pd(II) complexes, [PdClL1]•solvent (A1) and [PdClL2]•2H2O (A2) (L1 = 4′-(4-carboxyl-phenyl)-2,2′:6′,2”-terpyridine, L2 = 2,6-bis(2-pyrazinyl)-4-(4-carboxyl-phenyl)pyridine), from 4′-(4-cyanophenyl)-2,2′:6′,2”-terpyridine (L1a)/2,6-bis(2-pyrazinyl)-4-(4-cyanophenyl)pyridine (L2a) and Pd(II) acetate and characterize them by several instrumental techniques. A1 and A2 are good catalysts for the coupling of 2-iodobiphenyl with iodobenzenes to afford triphenylenes, which is known to involve dual C-H bond activation and double C-C bond formation. The obtained data suggest that the mechanism of A1-and A2-mediated coupling may be similar to the reference Pd catalysts, A1 and A2 are also suitable catalysts for this cyclization process. Study on this kind of complexes is of importance to the development of novel Pd-based catalysts and triphenylene synthesis techniques. The experimental part of the paper was very detailed, including the reaction process of 1-Chloro-3-iodobenzene(cas: 625-99-0Synthetic Route of C6H4ClI)
1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Synthetic Route of C6H4ClI
