Abstract : Low-coordination phosphorus compounds of various types (RO-PO2, R-PO2, RO-P(S)O, R-P=CH2) were generated in the presence of suspended solids known to contain surface OH groups (silica gel, alumina, Zeolites, titanium dioxide). In all cases, the phosphorus atom became covalently attached to the 0 atom on the surface. CP-MAS 31P NMR was used extensively to prove the presence of the bonded group. Valuable HPLC characteristics were found for phosphorylated silica gel.
