| 摘要: 本文合成了双金属配合物重铬酸四吡啶合镍(Ⅱ)[Py4Ni(HCrO4)2,TPND],晶体结构解析表明,TPND是一个以Ni(Ⅱ)为中心的正八面体配合物,而每两个分子之间由两个Cr-O-Cr桥相连接。并对TPND的氧化性质进行了研究,发现其具有很高的脱氢活性,对芳香酮腙的脱氢氧化产率较高(81%～91%)。 |

| Abstract: A new bimetallic coordination compound tetrakis-pyridine nickel (Ⅱ) dichromate [Py4Ni(HCrO4)2, TPND] was synthesized and its structure was confirmed by single crystal X-ray diffraction analysis. TPND showed very strong ability of dehydrogenation. Thus diarylethanedione dihydrazones (1) were converted to 1,2-diaryacetylenes (2) in 81%～91% promoted by TPND under very mild conditions. |
