Palladium-catalyzed ring-opening reactions of C1 substituted 7-oxanorbornadiene derivatives with aryl iodides were investigated. The optimal conditions for this reaction were found to be PdCl2(PPh3)2, ZnCl2, Et3N and Zn in THF. Both steric and electronic factors played a role in the outcome of the reaction as increasing the steric bulk on the bridgehead carbon decreased the yield. These reactio...
PdCl2, ZnCl2 and CuCl2 complexes of three benzimidazole derivatives two Schiff bases having the ferrocene group were synthesized characterized. It was unexpectedly noticed that Pd(II) Zn(II) exhibit paramagnetic characters corresponding to about one electron caused by moiety. For same reason, magnetic moment value Cu(II) also higher than anticipated values. Besides, antimicrobial activity inves...
The reaction of ArTe~ (Ar — 4-MeOC6H4) and Te" generated in situ by borohydride reduction of Ar2Te2 and Te, respectively, with 2-(2-thienyl)ethyl chloride has resulted in 2-[2-(4-methoxyphenyltelluro)ethyl]thiophene (L) and bis[2-(2-thienyl)ethyl] telluride (L), respectively. Their complexes [AgNO3(L)] (1) [PdCl2(L)2] (2) [PtCl2(L )2] (3) [HgBr2(L )]2 (4) [Ru(p-cymene)Cl2(L )] (5) [Ru(p-cymene)...
Suzuki-Miyaura coupling reaction catalyzed by the palladium (Pd)-based nanomaterials is one of the most versatile methods for the preparation of biaryls. However, use of organic solvents as reaction medium causes a big threat to environment due to the generation of toxic byproducts as waste during the work up of these reactions. Therefore, the use of water as reaction media has attracted tremen...
