摘要：

The tungsten(II) carbonyl compound (CO)(4)W(mu-Cl)(3)W(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 H-1 and C-13 NMR spectroscopy. On the basis of H-1 NMR monitoring of several catalytic reactions, a possible mechanism involving coordination of norbornene to the W(II) atom and its activation has been proposed.
