The 19F and 1H high resolution NMR spectra of the (p-fluorophenyl)chlorostannanes (FC6H4)nSnCl4-n have been observed at room temperature. The NMR parameters have been compared with the molecular structures and are in accord with the view that pπ}-dπ} interaction occurs between the phenyl ring π-orbital and the empty 4d tin orbital when n > 2.
在室温下观察到了(对
氟苯基)
氯锡烷(FC 6 H 4)n SnCl 4 -n的19 F和1 H高分辨率NMR光谱。已将NMR参数与分子结构进行了比较,并符合以下观点:当n > 2时,苯环π轨道与空的4 d
锡轨道之间会发生p π} -d π}相互作用。
