A study was carried out on the effect of the phosphine ligand structure on the rate and regioselectivity of the hydrocarboxylation of 1-heptene in dioxane in the presence of the PdCl/sub 2/(PR/sub 3/)/sub 2/-PR/sub 3/ catalytic system (R = aryl, alkyl). An increase in the basicity of phosphines with similar conic angle values leads to a decrease in the reaction rate and increase in selectivity. An increase in the conic angle in phosphines with similar pK/sub a/ values leads to a decrease in the selectivity relative to formation of the linear isomer.
