Table : Experimental and predicted regioselectivities for the reactions shown in Figure . The experimental values are from references 17 and 18 (the latter is indicated by a *). The neutral results are obtained with monodentate (PPh 3 ) 2 Pd-ligands and X=I, while the cationic results are obtained for X=triflate and the bidentate DPPP ligand. α, β, and "m" indicate the predicted selectivity or a mix where the two isomers are within 3 kcal/mol ≈ 12.6 kJ/mol. EDG and EWG indicate whether the alkene R-group is electron donating and withdrawing, respectively. The letters in the left-most side indidate the label used in reference 17 . As discussed in the text our method is not expected to be able to predict all cases where a mix should be observed for the neutral pathway.
