    • Currently we have full elemental analyses for these complexes of FC-1029 series (see Supporting Information, Preliminary solid state 31P NMR data of the FibreCat samples were obtained with the help of Prof. Mark Smith, Warwick University. FibreCat-1029 was used as a standard. FibreCat-1029 gave a single broad peak at 30-35 ppm, with associated spinning side-bands. This is assigned to be polymer-bound-PPh2 complexed to Pd(II, For FibreCat-1032 the main peak for-PPh2 is shifted to ca. 20 ppm (presumably due to trans effect of the PtBu3 ligand displacing MeCN) in addition to a new peak at ca. 40 ppm. The area for the second peak is smaller than that Of-PPh2, suggesting incomplete substitution with the bulky t-Bu3P ligand. As expected, where the added ligand contains only aryl substituents, as is the case for BINAP FibreCat-1036, separate resonances are not resolved. For FibreCat-1039, containing the polymer-b
    • 2 groups remain unreacted with Pd. The presence of these additional sites further complicates the spectral interpretation for FibreCat-1045 and -1046. Therefore detailed solid state NMR and surface characterization studies are required.
