The tungsten(II) carbonyl compound (CO)4W(μ-Cl)3W(SnCl3)(CO)3 has been found to be a very effective catalyst for the hydroarylation of bicyclo[2.2.1]hept-2-ene (norbornene) conducted in arene solution at room temperature. Norbornene adducts with benzene, toluene, para-xylene, and mesitylene have been isolated and their structures have been unambiguously established by means of 1H and 13C NMR spectroscopy
已发现羰基钨(II)化合物(CO)4 W(μ-Cl)3 W(SnCl 3)(CO)3是双环[2.2.1]庚-2-酯加氢芳构化的非常有效的催化剂烯(降冰片烯)在室温下在芳烃溶液中进行。分离出了降冰片烯与苯,甲苯,对二甲苯和均三甲苯的加合物,并通过1 H和13 C NMR光谱明确地确定了它们的结构。基于几个催化反应的1 H NMR监测,提出了一种可能的机制,涉及降冰片烯与W(II)原子的配位及其活化。
