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 ).
