摘要：

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.
