The product was characterized by infrared analysis, H NMR analysis and melting point measurement. The effects of catalyst molar ratio and reaction temperature were examined. The results showed that on the condition of n (benzyl chloride)∶ n (Fe)∶ n (Cu 2Cl 2)= 1 8∶1∶0 02, at 90 ℃, 86 7% yield could be achieved.展开更多
Two binuclear copper(I) complexes with novel structures and novel bonding,Cu_2(Ph_2PCH_2PPh_2)Cl_2 (Ph_2PCH_2PPh_2=dppm) and Cu_2(Ph_2P-CH_2CH_2PPh_2)Cl_2 (Ph_2PCH_2CH_2PPh_2=dppe), were prepared and characterized thr...Two binuclear copper(I) complexes with novel structures and novel bonding,Cu_2(Ph_2PCH_2PPh_2)Cl_2 (Ph_2PCH_2PPh_2=dppm) and Cu_2(Ph_2P-CH_2CH_2PPh_2)Cl_2 (Ph_2PCH_2CH_2PPh_2=dppe), were prepared and characterized through elemental analyses, ICP, IR(4000-200 cm^(-1), CsI disc.), ^(31)P-NMR spectra. Their electronic conductivities, oxidation and reduction potentials were measured. Preliminary studies show that both of the two complexes have chlorobridging and phosphorus-bridging structures.展开更多
