Abstract
The reaction of [Ru2(CO)4(µ-H)(µ-PtBu2)(µ-Ph2PCH2PPh2)] (1) with the diazonium salts [PhN2]BF4 and [p-BrC6H4N2]BF4 in dichloromethane at T = 273 K was investigated. The oxidative addition afforded the products [Ru2(CO)4(µ-H)(µ-PtBu2)(µ-Ph2PCH2PPh2)(µ-N2Ph)]BF4 (2a) and [Ru2(CO)4(µ-H)(µ-PtBu2)(µ-Ph2PCH2PPh2)(µ-N2C6H4-p-Br)]BF4 (2b) in good yields. The products have been characterized by NMR and IR spectroscopy and mass spectrometry and the molecular structure of 2a has been determined by a single-crystal X-ray diffraction analysis (monoclinic, space group P21/m, Z = 2).
研究了[Ru2(CO)4(µ-H)(µ-PtBu2)(µ-Ph2PCH2PPh2)](1)与重氮盐[PhN2]BF4 和[p-BrC6H4N2]BF4 在二氯甲烷中于 T = 273 K 的反应。氧化加成产物为[Ru2(CO)4(µ-H)(µ-PtBu2)(µ-Ph2PCH2PPh2)(µ-N2Ph)]BF4(2a)和[Ru2(CO)4(µ-H)(µ-PtBu2)(µ-Ph2PCH2PPh2)(µ-N2C6H4-p-Br)]BF4(2b),收率良好。这些产物已通过核磁共振、红外光谱和质谱法进行了表征,2a 的分子结构已通过单晶 X 射线衍射分析(单斜,空间群 P21/m,Z = 2)确定。
