Immobilisation of 4-Bromobenzoic Acid on Silica 1 4-Bromobenzoic acid (1.99 g, 10 mmol) was refluxed with dry SOCl 2 (20 mL) for 3 h. After that the solution was cooled and thionyl chloride was distilled off to give 4-bromobenzoyl chloride as a white solid. 3-Aminopropyl trimethoxysilane-modified silica (1.00 g, Aldrich), pyridine O O Si OR NH 2 Br Cl O O O Si OR NH O Br Pyridine, 12 h, 40 o C Scheme S1.
