Ruthenium porphyrin catalysed direct intermolecular amino-oxyarylation of alkenes including styrenes and 1,3-dienes to give primaryamines with O-(2,4-dinitrophenyl)hydroxylamine as the amine source was achieved in moderate to good yields under mild reaction conditions. Spectroscopic analyses revealed that a ruthenium nitrido complex was the key reaction intermediate for the amino-oxyarylation reaction
A practical copper-catalyzedhighlyregioselective 1,2-hydrocarboxylation of terminal 1,3-diene with carbon dioxide has been developed. Under mild reactionconditions, this chemistry afforded 2-benzyl-β,γ-unsaturated acid derivatives as products, which are a kind of important unit for bio-active molecules and versatile precursors for organic synthesis, with good functional group tolerance. The key

silylarylation of 1,3-dienes using chlorosilanes and aryl bromides is reported. The reaction affords 1,2-linear-silylated products, a selectivity that is distinct from those obtained with conventional hydro- and carbosilylation methods. This work shows the possibility to achieve the silyl-functionalization of unsaturated bonds using readily available chlorosilanes.
