trimethylamine (TMA) with boron trihalides (BX 3 ; X=F, Cl, Br) are reported, and interpreted with the aid of ab initio SCF MO calculations. The shift in the binding energy of the amine lone-pair orbital n N correlates well with the calculated net charge transferred and structural changes upon complexation. The results confirm that the donor-acceptor interaction is stronger in the complexes TMA·BCl 3 and TMA·BBr
摘要 报道了三甲胺 (TMA) 与三卤化硼 (BX 3 ; X=F, Cl, Br) 加成化合物的气相 HeI 光电子能谱和固相 X 射线光电子能谱,并借助从头算 SCF MO 计算。胺孤对轨道 n N 的结合能的变化与计算的净电荷转移和络合时的结构变化密切相关。结果证实,配合物TMA·BCl 3 和TMA·BBr 3 中的供体-受体相互作用比氟类似物更强。
