Abstract
A novel method to prepare a solid acid catalyst through the reaction of a metal-alkyl halide species and the surface hydroxyl group of a solid support is disclosed. Lewis acidic metals, e.g., B, Al and Ga, etc., can then be anchored on the surface via the formation of an oxygen-metal bond. The solids containing these metals can be used as catalysts that will catalyze organic compound coversion reactions, e.g., Friedel-Crafts type reactions, olefin oligomerization, aromatic alkylation and acylation, alkane alkylation and isomerization reactions.
