本文报道了钯催化的芳基三氟甲磺酸酯与不对称烯烃在双齿膦配体存在下的芳基化反应。这些配体的使用增加了电子因素在决定反应的区域选择性中的影响。催化剂的性能允许重访的方案，描述了赫克型反应的区域选择性的结果。此外，提出了钯催化烯烃芳基化反应的一般机理。
The palladium-catalyzed arylation of several unsymmetrical olefins by aryl triflates in the presence of bidentate phosphine ligands is described. The use of these ligands increases the influence that electronic factors have in determining regioselectivity of the reaction. The catalyst performances allow a revisiting of the scheme that describes the regioselectivity outcome in Heck-type reactions. Furthermore, a general mechanism for the palladium-catalyzed arylation of olefins is proposed.
