硫(IV)化合物作为配体:XX。噻吩-1-氧化物与有机锡卤化物的加合物形成和开环。的晶体结构[(4- FC 6 H ^ 4)2的SnCl 2(C 2 H ^ 4 SO)2 ]
摘要:
有机锡卤化物R n SnX 4- n(RPh,4-MeC 6 H 4,4 -FC 6 H 4 ; X Br Cl,Br; n = 0,1,2,3)和Me 2 SnCl 2形成与1,1-氧杂硫杂环丁烷加成。通常,对于n = 0、1、2,它们的化学计量比为1:2,并且是八面体的,如[(4-FC 6 H 4)2 SnCl 2(C 2 H 4 SO )的单晶结构研究所示。)2 ](4c)。在4c中,芳基是彼此互反,氯化物和亚砜配体互相顺。SO键比未配位的噻吩-1-氧化物中的键长0.04Å,而三元环中的键缩短了相似的量。取决于反应条件,可以有1:1的加合物[R 2 SnX 2(C 2 H 4 SO)](R = 4-MeC 6 H 4,XCl,Br; RMe,t也可以分离Bu,XCl),而三有机锡卤化物仅形成1:1的复合物。已经合成了类似的二甲基亚砜(DMSO)加合物用于比较。根据振动光谱数

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.
