对氟苯基异氰(CNPhpF)与[Re(CO)5 Br]在羰基配体的逐步交换下反应,取决于所应用的条件。反应停止,在沸腾的四氢呋喃中形成ac-[Re(CO)3Br(CNPhpF)2]。在较高温度下观察到进行中的羰基交换,例如,在无水甲苯中,最终形成[Re(CNPhpF)6]+阳离子。通过19 F NMR谱研究了反应过程,并通过X射线衍射确定了[Re(CO)Br(CNPhpF)4]和[Re(CNPhpF)6](BPh 4)的结构。
p‐Fluorophenylisocyanide (CNPhpF) reacts with [Re(CO)5Br] under stepwise exchange of the carbonyl ligands depending on the conditions applied. The reaction stops with the formation offac‐[Re(CO)3Br(CNPhpF)2] in boiling THF. An ongoing carbonyl exchange is observed at higher temperatures, e. g. in refluxing toluene, with the final formation of the [Re(CNPhpF)6]+cation. The progress of the reactions has been studied by19F NMR spectroscopy and the structures of [Re(CO)Br(CNPhpF)4] and [Re(CNPhpF)6](BPh4) have been elucidated by X‐ray diffraction.
