3-tetrachloroheptane. These mixed ligated complexes 1a–g afforded the higher yield of the radical addition product than a homoleptic DAniF complex, [Mo2(DAniF)4] (2). Among them, complexes 1a and 1g gave the radical addition product quantitatively after 9 h with a short induction period. When complexes 1a and 1g were treated with CCl4, we detected the mixed-valence Mo2(II/III) complex, [Mo2(DAniF)3Cl2] (4), in electrospray
                                    我们合成了一系列混合的连接的三(酰胺基)二

DAniF复合物[Mo 2(
DAniF)4 ](2)提供更高的自由基加成产物收率。其中,络合物1a和1g在9 h后以较短的诱导期定量给出了自由基加成产物。当用CCl 4处理配合物1a和1g时,我们检测到混合价的Mo 2(II / III)配合物[Mo 2(
