英文摘要: Lignin is the primary source of aromatic chemicals in nature. Selective aerobic oxidation has provided a promising approach for breaking lignin into smaller aromatics. During VO(acac)(2)-catalyzed oxidation of lignin model compound 2-phenoxy-1-phenylethanol, benzaldehyde was unexpectedly observed as a product, in contrast to the results reported previously. The reaction pathway was studied, and a hemiacetal-like intermediate was found to be involved, and the similar intermediate was also observed during oxidation of model compound benzyl phenyl ether. Compared with direct C-O bond cleavage, prior formation of hemiacetal-like structures via oxidation would be expected to facilitate the cleavage of the aryl ether bond in aralkyl aryl ethers under mild reaction conditions.
