Norbornene and norbornadiene derivatives have been shown to react with aryl and vinyl halides in the presence of a palladium catalyst, formic acid, and tributylamine or piperidine to give hydroarylated and hydrovinylated derivatives in good to high yield. Extension of the reaction to the hindered α,β-unsaturated aldehydic system of myrtenal produced a monocyclic derivative through a palladium-catalyzed
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。

exo-2-Chloro- and 7-chloronorbornane in the presence of tin(IV) chloride or aluminum chloride react with benzene and substituted benzenes to give the corresponding norbornylated products. Mechanistic aspects of the reactions proceeding through carbocationic intermediates are discussed.
New Phosphine-Functionalized N-Heterocyclic Carbene Ligands for Palladium-Catalyzed Hydroarylation Reaction
bicyclic olefins. Under reductive conditions (HCOOH, Et 3 N), the complexes generated in situ from imidazolinium salts and Pd(OAc) 2catalyzed the hydroarylation of bicyclic alkenes with aryl iodides, providing the hydroarylation products with high turnover numbers (TON, up to 1.9·10 5 ) and turnover frequencies (TOF, up to 6.3·10 4 ).
