Resum
13C NMR differences of chemical shifts (δX - δH) of allyl carbon atoms in a series of trans-(1-(diphenylphospnino)-2-(dimethylamino)ethane)(η 3-1-arylallyl)palladium tetrafluoroborates, X ranging from NO2 to OMe, correlate very well with σ Hammett constants for C-1 and with σ+ for C-3, this carbon atom being in a irons relationship with the positively charged nitrogen atom.
