Since the nuclear attack on a triple bond is not carried out, the use of palladium catalyst is considered a suitable route for the activation of these compounds. In this study, a new pathway for the preparation of styrene derivatives using alcohols As a source of active vinyl and boronic acids, it has been reported as a source of activated Ariel. Optimum reaction conditions include the catalytic system of tris (diphenzilindenson) palladium / 1 and 4- bis (phenylphosphine) butane as a ligand and a mixture of dimethyl acetamide/water as a solvent. The study of variation reacted that the presence of fatal electron and electron components in the structure of boronic acids ariel is very well suited to the reaction conditions. In addition, the selectivity test reacts that the reaction product is predominantly cysteine. %U https://www.nsmsi.ir/article_32281_19e2cd63bea7611fdd63de735ab7d393.pdf
