Synthesis Materials and Apparatus. All manipulations were carried out in an atmosphere of purified and dry dinitrogen using standard Schlenk line techniques unless otherwise stated. Solvents were dried from the appropriate drying agent, degassed and stored under nitrogen. All commercially available starting materials were not further purified unless otherwise stated. 1 H, 31 P, and 13 C NMR spectra were recorded on either a JEOL-EX270 or a Bruker Avance 400 Ultrashield NMR spectrometer ( 270.17

IR spectra were recorded on Research Series FT-IR using KBr disks in the range 4000-500 cm -1 . Pd(dppp)Cl 2 and Pd(dppp)(OTf) 2 were synthesized by adaptation of previously reported procedures. 1,2 # Supplementary Material (ESI) for Chemical Communications # This journal is
