ALKYLATION OF ANIONS ON SOLID INORGANIC SUPPORTS : AN INTERPRETATION OF THE FUNCTIONS OF THE SUPPORTS

Article abstract of DOI:10.1016/S0040-4039(00)71118-X

In the anionic alkylation (CH3CO2K + n C8H17Br) on solid inorganic supports, silica impregnated with cationic surfactant appear to be as effective as alumina, while silica bearing ammonium groups covalently bonded to the support (SPHEROSIL QMA) exhibits increased effectiveness.An interpretation based upon the superficial charge of the solid surfaces is proposed.
