We report an efficient means of sp2–sp3 crosscoupling for a variety of terminal monosubstituted olefins with aryl electrophiles using Pd and CuH catalysis. In addition to its applicability to a range of aryl bromide substrates, this process was also suitable for electron‐deficient aryl chlorides, furnishing higher yields than the corresponding aryl bromides in these cases. The optimized protocol does

heteroarenes with unactivated alkenes by Au(III)-catalyzedintermolecularhydroarylationunder mild reaction conditions was developed. This method features a short reaction time (5 h) under mild conditions and has a broad substrate scope, including electron-rich arenes and heteroarenes, terminal and internal substituted aryl alkenes, and unactivated aliphatic alkenes.
1,5-Cyclooctdiene reacted with phenylpalladium chloride to give di-μ-chloro-bis-(1-phenylcyclooct-4-ene-8σ,4π)-dipalladium(II). Similarly, the reaction of endo-dicyclo-pentadiene with phenylpalladium chloride led to di-μ-chloro-bis-[endo-6-phenyl-3a,4,5,6,7,7a-hexahydro-endo-4,7-methanoindene-endo-5σ,(2–3)π]-dipalladium (II). The σ-bonded structures of these complexes have been confirmed by studies
