E = O, S). In the crystals, the two molecules with -PCl2 substituents adopt trans conformations, while the other two have the -P(NEt2)2 groups rotated into a twist conformation. The reaction of the thienyl compounds with tris[(tert-phosphine)gold]oxonium tetrafluoroborates gave almost quantitative yields of the tri- and hexanuclear gold complexes, respectively: 2-C4H3S-P[Au(PR3)]3}+BF4- and [2,5-
伯和二伯杂芳基膦R-PH2和H2P-R'-PH2的便捷高产合成(R = 2-噻吩基,2-呋喃基,R'= 2,5-噻吩二基,2,5 -呋喃二基)。已通过分析和光谱数据对产物和一组前体分子进行了表征,并确定了所选分子的晶体结构:2-C4H3O-PCl2、2,5-(Cl2P)2C4H2O,2,5-[(Et2N) )2P] 2C4H2E(其中E = O,S)。在晶体中,两个具有-PCl2取代基的分子采用反式构象,而另外两个具有-P(NEt2)2基团旋转成扭曲构象的分子。噻吩基化合物与三[(叔膦)金]四氟硼酸ox的反应几乎分别定量获得了三核和六核金配合物:2-C4H3S-P [Au(PR3)] 3} + BF4-和[2,
