Abstract

The synthesis of p-acetyl and p-benzoyl derivatives of various benzylsilanes (p-R1CO– C6H4–CR2R3–SiMe3: R1, R2, R3= Me, H, H; Me, H, Ph; Me, H, Me; Me, Me, Me; Ph, H, H; Ph, H, Ph; Ph, H, Me; Ph, Me, Me), xanthenes (3-benzoyl and 3, 6-dibenzoyl), and 9-Me3Si- xanthenes (3-benzoyl, 3, 6-dibenzoyl, 3-acetyl and 3, 6-diacetyl) using Friedel–Crafts reactions and typical Lewis acid catalysts (AlCl3, FeCl3, ZnCl2) is described.
