Solid‐state NMR spectroscopy of selected phosphine oxides adsorbed on silica surfaces establishes the surface mobilities, even of phosphine oxides with high melting points. Crystal structures of the adducts Ph3PO⋅HOSiPh3and Cy3PO⋅H2O indicate that the interactions with silica involve hydrogen bonding of the PO group to adsorbed water and surface silanol groups.
