The present invention relates to a process for the arylation of olefins by reaction of haloaromatics or arylsulfonates with olefins in the presence of a palladium catalyst, a bulky nitrogen base and a salt.
Highly regio- and enantioselective hydrogenation of conjugated α-substituted dienoic acids was realized for the first time using Trifer–Rh complex, providing a straightforward method for the synthesis of chiral α-substituted γ,δ-unsaturated acids. DFT calculations revealed N+H–O hydrogen bonding interaction is formed to stabilize the transition state and the coordination of 4,5-double bond to Rh(III)
