二苯甲酮与含有1，2-双[（2，6-二异丙基苯基）亚氨基]苊的镁配合物[（2，6-iPr（2）C（6）H（3）-bian）Mg（thf）]（1）还原，得到频哪醇配合物[（2，6-iPr（2）C（6）H（3）-bian）Mg（thf）]（2）[mu-O2 C2 Ph 4]（.）（C6H6）（4）（2）. 1与9（10 H）-蒽酮反应生成9-蒽酚配合物[（2，6-iPr（2）C（6）H（3）-bian）Mg（OC 14 H9）（thf）（2）]（3）。配合物2和3通过元素分析、UV/维斯、IR和ESR光谱以及单晶X-射线衍射进行了表征。配合物2在溶液中解离，桥接频哪醇单元分裂，形成双自由基二亚氨基/酮基配合物[（2，6-iPr（2）C（6）H（3）-bian）Mg（thf）（OCPh 2）]。
The reduction of benzophenone with the magnesium complex [(2,6-iPr(2)C(6)H(3)-bian)Mg(thf)(3)] (1), containing the 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene dianion, affords the pinacolato complex [(2,6-iPr(2)C(6)H(3)-bian)Mg(thf)](2)[ mu-O2C2Ph4](.)(C6H6)(4) (2). The reaction of 1 with 9(10H)-anthracenone yields the 9-anthracenolato complex [(2,6-iPr(2)C(6)H(3)-bian)Mg(OC14H9)(thf)(2)] (3). Complexes 2 and 3 were characterized by elemental analyses, UV/Vis, IR, and ESR spectroscopy, as well as by single crystal X-ray diffraction. Complex 2 dissociates in solution with splitting of the bridging pinacolato unit, forming the biradical diimino/ketyl complex [(2,6-iPr(2)C(6)H(3)-bian)Mg(thf)(OCPh2)].
