Abstract
C-13 NMR chemical shifts of the terminal allyl carbon atoms C-1 and C- 3 of (1, 2-bis(diphenylphosphino)ethane)(eta(3)-1, 3-diarylallyl)palla dium tetrafluoroborates correlate with sigma Hammett substituent const ants. For each complex the chemical shift at lower field indicates the site of preferred attack by soft nucleophiles in the Tsuji-Trost reac tion.
