Direct acylation of imidazo [1,2-a] pyridines in a sealed tube at 130°C and without catalyst gave various 3-acyl derivatives in satisfactory yields.

Group 5 and 6 metal chlorides such as MoCl5, WCl6, NbCl5 and TaCl5 were found as very efficient catalysts for acylative cleavage of the C-O bond of ethers. Compared with conventional Lewis acid catalysts such as ZnCl2, AlCl3, SnCl4 and TiCl4, group 5 and 6 metal chlorides showed better results in the catalytic C-O bond cleavage of dibutyl ether with benzoyl chloride.
