Alkylsilylated gold loaded magnesium oxide aerogel catalyst in the oxidation of styrene

Aerogel-prepared magnesium oxide (A-MgO) was modified by attachment of gold particles. Subsequent modification of its surface with alkylsilylation of n-octadecyltrichlorosilane and chlorotrimethylsilane exhibits a high catalytic activity for oxidation of styrene with tert-butyl hydroperoxide in liqu...
