Some alkynes were diarylated by aryltributylstannane 2 in the presence of palladium salt in moderate to good yield with high stereoselectivity. The reaction was catalytic in palladium using copper(II) chloride dihydrate as a reoxidant.

We report herein an alkenylation of benzylic C(sp3)-H bonds with diazo compounds via carbon cation intermediates with DDQ as the oxidant in the presence of a catalytic amount of Fe(ii). Diphenylmethane, toluene, benzyl methyl sulfide and their derivatives could be applied as substrates to afford the tetra-substituted olefin products, which may serve as useful building blocks in organic synthesis.
Nickel-Catalyzed Arylative Carboxylation of Alkynes with Arylmagnesium Reagents and Carbon Dioxide Leading to Trisubstituted Acrylic Acids

Nickel-catalyzed arylcarboxylation of alkynes with arylmagnesium reagents and carbon dioxide (CO2, 1 atm) was realized in one pot. Various trisubstituted acrylic acids within an aryl group at the β-position have been prepared efficiently with good regioselectivity under mild conditions. The resulting products could be further transformed to benzoannelated cycles retaining CO2 as a one-carbon synthon.
