N,C,N-Chelated pnictinidenes ArE [where E = As (1), Sb (2) or Bi (3); Ar = CH-2,6-(CH[double bond, length as m-dash]Nt-Bu)] were used as ligands for the coordination of transition metal carbonyls. Thus, the reaction of 1-3 with [M(CO)THF] (where M = Cr, W) or [Mo(CO)(MeN)] gave complexes [(ArE)M(CO)] [where E = As and M = Cr (1a), Mo (1b), W (1c); E = Sb and M = Cr (2a), Mo (2b), W (2c); E = Bi and M = Cr (3a), Mo (3b), W (3c)]. Analogously, the treatment of 1-3 with [Fe(CO)] resulted in the formation of the complexes [(ArE)Fe(CO)] [where E = As (1d), Sb (2d) or Bi (3d)]. All compounds were characterized by H and C NMR spectroscopy, Raman, IR and UV-Vis spectroscopy. The molecular structures of the majority of the compounds (except 1b and 1c) were also determined by the single-crystal X-ray diffraction analysis. Furthermore, the structure and bonding of the title compounds have also been thoroughly investigated using a computational approach.
N、C、N-螯合的磷族元素化合物ArE(其中E = As(1)、Sb(2)或Bi(3);Ar = CH-2,6-(CH[双键,长度如间位短线]-Nt-Bu))被用作过渡金属羰基配合物的配体。因此,1-3与[M(CO)THF](其中M = Cr、W)或[Mo(CO)(MeN)]反应得到配合物[(ArE)M(CO)](其中E = As且M = Cr(1a)、Mo(1b)、W(1c);E = Sb且M = Cr(2a)、Mo(2b)、W(2c);E = Bi且M = Cr(3a)、Mo(3b)、W(3c))。类似地,1-3与[Fe(CO)]反应生成配合物[(ArE)Fe(CO)](其中E = As(1d)、Sb(2d)或Bi(3d))。所有化合物均通过氢谱和碳谱核磁共振、拉曼光谱、红外光谱和紫外-可见光谱进行表征。大多数化合物(1b和1c除外)的分子结构也通过单晶X射线衍射分析确定。此外,还使用计算方法对标题化合物的结构和键合进行了深入研究。
