application of dimeric ortho-palladated complex of 2-methoxyphenethylamine in the heck coupling reaction

the application of the [pd{c6h3(ch2ch2nh2)-4-ome-5-κ2-c,n}(μ-br)]2 complex of 2-methoxyphenethylamine in the heck coupling reaction was considered under both conventional and microwave irradiation conditions, and their results were compared. this complex is an efficient, stable and non-sensitive to air and moisture catalyst for the vinylation of substituted aryl halides with different electronic properties. the cross-coupled products were produced in good to excellent yields using a catalytic amount of this complex in n-methyl-2-pyrrolidone (nmp) at 130 °c. in comparison to conventional heating conditions, the reactions under microwave irradiation gave higher yields in shorter reaction times.
